Version 2, June 1991

|
||||||

|
|
||||||
Everyone is permitted to copy and distribute verbatim copies
|
|
||||||
of this license document, but changing it is not allowed.
|
|
||||||
|
|
||||||
Preamble
|
|
||||||
|
|
||||||
The licenses for most software are designed to take away your
|
|
||||||
freedom to share and change it. By contrast, the GNU General Public
|
|
||||||
License is intended to guarantee your freedom to share and change free
|
|
||||||
software--to make sure the software is free for all its users. This
|
|
||||||
General Public License applies to most of the Free Software
|
|
||||||
Foundation's software and to any other program whose authors commit to
|
|
||||||
using it. (Some other Free Software Foundation software is covered by
|
|
||||||
the GNU Lesser General Public License instead.) You can apply it to
|
|
||||||
your programs, too.
|
|
||||||
|
|
||||||
When we speak of free software, we are referring to freedom, not
|
|
||||||
price. Our General Public Licenses are designed to make sure that you
|
|
||||||
have the freedom to distribute copies of free software (and charge for
|
|
||||||
this service if you wish), that you receive source code or can get it
|
|
||||||
if you want it, that you can change the software or use pieces of it
|
|
||||||
in new free programs; and that you know you can do these things.
|
|
||||||
|
|
||||||
To protect your rights, we need to make restrictions that forbid
|
|
||||||
anyone to deny you these rights or to ask you to surrender the rights.
|
|
||||||
These restrictions translate to certain responsibilities for you if you
|
|
||||||
distribute copies of the software, or if you modify it.
|
|
||||||
|
|
||||||
For example, if you distribute copies of such a program, whether
|
|
||||||
gratis or for a fee, you must give the recipients all the rights that
|
|
||||||
you have. You must make sure that they, too, receive or can get the
|
|
||||||
source code. And you must show them these terms so they know their
|
|
||||||
rights.
|
|
||||||
|
|
||||||
We protect your rights with two steps: (1) copyright the software, and
|
|
||||||
(2) offer you this license which gives you legal permission to copy,
|
|
||||||
distribute and/or modify the software.
|
|
||||||
|
|
||||||
Also, for each author's protection and ours, we want to make certain
|
|
||||||
that everyone understands that there is no warranty for this free
|
|
||||||
software. If the software is modified by someone else and passed on, we
|
|
||||||
want its recipients to know that what they have is not the original, so
|
|
||||||
that any problems introduced by others will not reflect on the original
|
|
||||||
authors' reputations.
|
|
||||||
|
|
||||||
Finally, any free program is threatened constantly by software
|
|
||||||
patents. We wish to avoid the danger that redistributors of a free
|
|
||||||
program will individually obtain patent licenses, in effect making the
|
|
||||||
program proprietary. To prevent this, we have made it clear that any
|
|
||||||
patent must be licensed for everyone's free use or not licensed at all.
|
|
||||||
|
|
||||||
The precise terms and conditions for copying, distribution and
|
|
||||||
modification follow.
|
|
||||||
|
|
||||||
GNU GENERAL PUBLIC LICENSE
|
|
||||||
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
|
|
||||||
|
|
||||||
0. This License applies to any program or other work which contains
|
|
||||||
a notice placed by the copyright holder saying it may be distributed
|
|
||||||
under the terms of this General Public License. The "Program", below,
|
|
||||||
refers to any such program or work, and a "work based on the Program"
|
|
||||||
means either the Program or any derivative work under copyright law:
|
|
||||||
that is to say, a work containing the Program or a portion of it,
|
|
||||||
either verbatim or with modifications and/or translated into another
|
|
||||||
language. (Hereinafter, translation is included without limitation in
|
|
||||||
the term "modification".) Each licensee is addressed as "you".
|
|
||||||
|
|
||||||
Activities other than copying, distribution and modification are not
|
|
||||||
covered by this License; they are outside its scope. The act of
|
|
||||||
running the Program is not restricted, and the output from the Program
|
|
||||||
is covered only if its contents constitute a work based on the
|
|
||||||
Program (independent of having been made by running the Program).
|
|
||||||
Whether that is true depends on what the Program does.
|
|
||||||
|
|
||||||
1. You may copy and distribute verbatim copies of the Program's
|
|
||||||
source code as you receive it, in any medium, provided that you
|
|
||||||
conspicuously and appropriately publish on each copy an appropriate
|
|
||||||
copyright notice and disclaimer of warranty; keep intact all the
|
|
||||||
notices that refer to this License and to the absence of any warranty;
|
|
||||||
and give any other recipients of the Program a copy of this License
|
|
||||||
along with the Program.
|
|
||||||
|
|
||||||
You may charge a fee for the physical act of transferring a copy, and
|
|
||||||
you may at your option offer warranty protection in exchange for a fee.
|
|
||||||
|
|
||||||
2. You may modify your copy or copies of the Program or any portion
|
|
||||||
of it, thus forming a work based on the Program, and copy and
|
|
||||||
distribute such modifications or work under the terms of Section 1
|
|
||||||
above, provided that you also meet all of these conditions:
|
|
||||||
|
|
||||||
a) You must cause the modified files to carry prominent notices
|
|
||||||
stating that you changed the files and the date of any change.
|
|
||||||
|
|
||||||
b) You must cause any work that you distribute or publish, that in
|
|
||||||
whole or in part contains or is derived from the Program or any
|
|
||||||
part thereof, to be licensed as a whole at no charge to all third
|
|
||||||
parties under the terms of this License.
|
|
||||||
|
|
||||||
c) If the modified program normally reads commands interactively
|
|
||||||
when run, you must cause it, when started running for such
|
|
||||||
interactive use in the most ordinary way, to print or display an
|
|
||||||
announcement including an appropriate copyright notice and a
|
|
||||||
notice that there is no warranty (or else, saying that you provide
|
|
||||||
a warranty) and that users may redistribute the program under
|
|
||||||
these conditions, and telling the user how to view a copy of this
|
|
||||||
License. (Exception: if the Program itself is interactive but
|
|
||||||
does not normally print such an announcement, your work based on
|
|
||||||
the Program is not required to print an announcement.)
|
|
||||||
|
|
||||||
These requirements apply to the modified work as a whole. If
|
|
||||||
identifiable sections of that work are not derived from the Program,
|
|
||||||
and can be reasonably considered independent and separate works in
|
|
||||||
themselves, then this License, and its terms, do not apply to those
|
|
||||||
sections when you distribute them as separate works. But when you
|
|
||||||
distribute the same sections as part of a whole which is a work based
|
|
||||||
on the Program, the distribution of the whole must be on the terms of
|
|
||||||
this License, whose permissions for other licensees extend to the
|
|
||||||
entire whole, and thus to each and every part regardless of who wrote it.
|
|
||||||
|
|
||||||
Thus, it is not the intent of this section to claim rights or contest
|
|
||||||
your rights to work written entirely by you; rather, the intent is to
|
|
||||||
exercise the right to control the distribution of derivative or
|
|
||||||
collective works based on the Program.
|
|
||||||
|
|
||||||
In addition, mere aggregation of another work not based on the Program
|
|
||||||
with the Program (or with a work based on the Program) on a volume of
|
|
||||||
a storage or distribution medium does not bring the other work under
|
|
||||||
the scope of this License.
|
|
||||||
|
|
||||||
3. You may copy and distribute the Program (or a work based on it,
|
|
||||||
under Section 2) in object code or executable form under the terms of
|
|
||||||
Sections 1 and 2 above provided that you also do one of the following:
|
|
||||||
|
|
||||||
a) Accompany it with the complete corresponding machine-readable
|
|
||||||
source code, which must be distributed under the terms of Sections
|
|
||||||
1 and 2 above on a medium customarily used for software interchange; or,
|
|
||||||
|
|
||||||
b) Accompany it with a written offer, valid for at least three
|
|
||||||
years, to give any third party, for a charge no more than your
|
|
||||||
cost of physically performing source distribution, a complete
|
|
||||||
machine-readable copy of the corresponding source code, to be
|
|
||||||
distributed under the terms of Sections 1 and 2 above on a medium
|
|
||||||
customarily used for software interchange; or,
|
|
||||||
|
|
||||||
c) Accompany it with the information you received as to the offer
|
|
||||||
to distribute corresponding source code. (This alternative is
|
|
||||||
allowed only for noncommercial distribution and only if you
|
|
||||||
received the program in object code or executable form with such
|
|
||||||
an offer, in accord with Subsection b above.)
|
|
||||||
|
|
||||||
The source code for a work means the preferred form of the work for
|
|
||||||
making modifications to it. For an executable work, complete source
|
|
||||||
code means all the source code for all modules it contains, plus any
|
|
||||||
associated interface definition files, plus the scripts used to
|
|
||||||
control compilation and installation of the executable. However, as a
|
|
||||||
special exception, the source code distributed need not include
|
|
||||||
anything that is normally distributed (in either source or binary
|
|
||||||
form) with the major components (compiler, kernel, and so on) of the
|
|
||||||
operating system on which the executable runs, unless that component
|
|
||||||
itself accompanies the executable.
|
|
||||||
|
|
||||||
If distribution of executable or object code is made by offering
|
|
||||||
access to copy from a designated place, then offering equivalent
|
|
||||||
access to copy the source code from the same place counts as
|
|
||||||
distribution of the source code, even though third parties are not
|
|
||||||
compelled to copy the source along with the object code.
|
|
||||||
|
|
||||||
4. You may not copy, modify, sublicense, or distribute the Program
|
|
||||||
except as expressly provided under this License. Any attempt
|
|
||||||
otherwise to copy, modify, sublicense or distribute the Program is
|
|
||||||
void, and will automatically terminate your rights under this License.
|
|
||||||
However, parties who have received copies, or rights, from you under
|
|
||||||
this License will not have their licenses terminated so long as such
|
|
||||||
parties remain in full compliance.
|
|
||||||
|
|
||||||
5. You are not required to accept this License, since you have not
|
|
||||||
signed it. However, nothing else grants you permission to modify or
|
|
||||||
distribute the Program or its derivative works. These actions are
|
|
||||||
prohibited by law if you do not accept this License. Therefore, by
|
|
||||||
modifying or distributing the Program (or any work based on the
|
|
||||||
Program), you indicate your acceptance of this License to do so, and
|
|
||||||
all its terms and conditions for copying, distributing or modifying
|
|
||||||
the Program or works based on it.
|
|
||||||
|
|
||||||
6. Each time you redistribute the Program (or any work based on the
|
|
||||||
Program), the recipient automatically receives a license from the
|
|
||||||
original licensor to copy, distribute or modify the Program subject to
|
|
||||||
these terms and conditions. You may not impose any further
|
|
||||||
restrictions on the recipients' exercise of the rights granted herein.
|
|
||||||
You are not responsible for enforcing compliance by third parties to
|
|
||||||
this License.
|
|
||||||
|
|
||||||
7. If, as a consequence of a court judgment or allegation of patent
|
|
||||||
infringement or for any other reason (not limited to patent issues),
|
|
||||||
conditions are imposed on you (whether by court order, agreement or
|
|
||||||
otherwise) that contradict the conditions of this License, they do not
|
|
||||||
excuse you from the conditions of this License. If you cannot
|
|
||||||
distribute so as to satisfy simultaneously your obligations under this
|
|
||||||
License and any other pertinent obligations, then as a consequence you
|
|
||||||
may not distribute the Program at all. For example, if a patent
|
|
||||||
license would not permit royalty-free redistribution of the Program by
|
|
||||||
all those who receive copies directly or indirectly through you, then
|
|
||||||
the only way you could satisfy both it and this License would be to
|
|
||||||
refrain entirely from distribution of the Program.
|
|
||||||
|
|
||||||
If any portion of this section is held invalid or unenforceable under
|
|
||||||
any particular circumstance, the balance of the section is intended to
|
|
||||||
apply and the section as a whole is intended to apply in other
|
|
||||||
circumstances.
|
|
||||||
|
|
||||||
It is not the purpose of this section to induce you to infringe any
|
|
||||||
patents or other property right claims or to contest validity of any
|
|
||||||
such claims; this section has the sole purpose of protecting the
|
|
||||||
integrity of the free software distribution system, which is
|
|
||||||
implemented by public license practices. Many people have made
|
|
||||||
generous contributions to the wide range of software distributed
|
|
||||||
through that system in reliance on consistent application of that
|
|
||||||
system; it is up to the author/donor to decide if he or she is willing
|
|
||||||
to distribute software through any other system and a licensee cannot
|
|
||||||
impose that choice.
|
|
||||||
|
|
||||||
This section is intended to make thoroughly clear what is believed to
|
|
||||||
be a consequence of the rest of this License.
|
|
||||||
|
|
||||||
8. If the distribution and/or use of the Program is restricted in
|
|
||||||
certain countries either by patents or by copyrighted interfaces, the
|
|
||||||
original copyright holder who places the Program under this License
|
|
||||||
may add an explicit geographical distribution limitation excluding
|
|
||||||
those countries, so that distribution is permitted only in or among
|
|
||||||
countries not thus excluded. In such case, this License incorporates
|
|
||||||
the limitation as if written in the body of this License.
|
|
||||||
|
|
||||||
9. The Free Software Foundation may publish revised and/or new versions
|
|
||||||
of the General Public License from time to time. Such new versions will
|
|
||||||
be similar in spirit to the present version, but may differ in detail to
|
|
||||||
address new problems or concerns.
|
|
||||||
|
|
||||||
Each version is given a distinguishing version number. If the Program
|
|
||||||
specifies a version number of this License which applies to it and "any
|
|
||||||
later version", you have the option of following the terms and conditions
|
|
||||||
either of that version or of any later version published by the Free
|
|
||||||
Software Foundation. If the Program does not specify a version number of
|
|
||||||
this License, you may choose any version ever published by the Free Software
|
|
||||||
Foundation.
|
|
||||||
|
|
||||||
10. If you wish to incorporate parts of the Program into other free
|
|
||||||
programs whose distribution conditions are different, write to the author
|
|
||||||
to ask for permission. For software which is copyrighted by the Free
|
|
||||||
Software Foundation, write to the Free Software Foundation; we sometimes
|
|
||||||
make exceptions for this. Our decision will be guided by the two goals
|
|
||||||
of preserving the free status of all derivatives of our free software and
|
|
||||||
of promoting the sharing and reuse of software generally.
|
|
||||||
|
|
||||||
NO WARRANTY
|
|
||||||
|
|
||||||
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
|
|
||||||
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
|
|
||||||
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
|
|
||||||
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
|
|
||||||
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
|
|
||||||
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
|
|
||||||
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
|
|
||||||
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
|
|
||||||
REPAIR OR CORRECTION.
|
|
||||||
|
|
||||||
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
|
|
||||||
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
|
|
||||||
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
|
|
||||||
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
|
|
||||||
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
|
|
||||||
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
|
|
||||||
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
|
|
||||||
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
|
|
||||||
POSSIBILITY OF SUCH DAMAGES.
|
|
||||||
|
|
||||||
END OF TERMS AND CONDITIONS
|
|
||||||
|
|
||||||
How to Apply These Terms to Your New Programs
|
|
||||||
|
|
||||||
If you develop a new program, and you want it to be of the greatest
|
|
||||||
possible use to the public, the best way to achieve this is to make it
|
|
||||||
free software which everyone can redistribute and change under these terms.
|
|
||||||
|
|
||||||
To do so, attach the following notices to the program. It is safest
|
|
||||||
to attach them to the start of each source file to most effectively
|
|
||||||
convey the exclusion of warranty; and each file should have at least
|
|
||||||
the "copyright" line and a pointer to where the full notice is found.
|
|
||||||
|
|
||||||

Copyright (C) {year} {fullname}
|
|
||||||
|
|
||||||
This program is free software; you can redistribute it and/or modify
|
|
||||||
it under the terms of the GNU General Public License as published by
|
|
||||||
the Free Software Foundation; either version 2 of the License, or
|
|
||||||
(at your option) any later version.
|
|
||||||
|
|
||||||
This program is distributed in the hope that it will be useful,
|
|
||||||
but WITHOUT ANY WARRANTY; without even the implied warranty of
|
|
||||||
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
|
|
||||||
GNU General Public License for more details.
|
|
||||||
|
|
||||||
You should have received a copy of the GNU General Public License along
|
|
||||||
with this program; if not, write to the Free Software Foundation, Inc.,
|
|
||||||
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
|
|
||||||
|
|
||||||
Also add information on how to contact you by electronic and paper mail.
|
|
||||||
|
|
||||||
If the program is interactive, make it output a short notice like this
|
|
||||||
when it starts in an interactive mode:
|
|
||||||
|
|
||||||
Gnomovision version 69, Copyright (C) year name of author
|
|
||||||
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
|
|
||||||
This is free software, and you are welcome to redistribute it
|
|
||||||
under certain conditions; type `show c' for details.
|
|
||||||
|
|
||||||
The hypothetical commands `show w' and `show c' should show the appropriate
|
|
||||||
parts of the General Public License. Of course, the commands you use may
|
|
||||||
be called something other than `show w' and `show c'; they could even be
|
|
||||||
mouse-clicks or menu items--whatever suits your program.
|
|
||||||
|
|
||||||
You should also get your employer (if you work as a programmer) or your
|
|
||||||
school, if any, to sign a "copyright disclaimer" for the program, if
|
|
||||||
necessary. Here is a sample; alter the names:
|
|
||||||
|
|
||||||
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
|
|
||||||
`Gnomovision' (which makes passes at compilers) written by James Hacker.

This General Public License does not permit incorporating your program into
|
|
||||||
proprietary programs. If your program is a subroutine library, you may
|
|
||||||
consider it more useful to permit linking proprietary applications with the
|
|
||||||
library. If this is what you want to do, use the GNU Lesser General
|
|
||||||
Public License instead of this License.

# snap-pac
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
## Synopsis
|
|
||||||
|
|
||||||
This is a set of pacman hooks and script that automatically causes snapper to
|
|
||||||
perform a pre and post snapshot before and after pacman transactions, similar to
|
|
||||||
how YaST does with OpenSuse. This provides a simple way to undo changes to a
|
|
||||||
system after a pacman transaction.
|
|
||||||
|
|
||||||
## Installation
|
|
||||||
|
|
||||||
Install the `snap-pac` package using pacman.
|
|
||||||
|
|
||||||
Alternatively [download the latest release] and signature , verify the download, and
|
|
||||||
then run `make install`.
|
|
||||||
|
|
||||||
I have signed the release tarball and commits with my PGP key. Starting with release
|
|
||||||
2.2, the tarballs are signed with my key with fingerprint
|
|
||||||
`F7B28C61944FE30DABEEB0B01070BCC98C18BD66`.
|
|
||||||
|
|
||||||
For previous releases, the key's fingerprint was
|
|
||||||
`8535CEF3F3C38EE69555BF67E4B5E45AA3B8C5C3`.
|
|
||||||
|
|
||||||
## Configuration
|
|
||||||
|
|
||||||
Most likely, configuration is not needed. By default, the snapper configuration named
|
|
||||||
`root` will have pre/post snapshots taken for every pacman transaction.
|
|
||||||
|
|
||||||
To configure, copy the example configuration file:
|
|
||||||
|
|
||||||
```bash
|
|
||||||
cp /etc/snap-pac.ini{.example,}
|
|
||||||
```
|
|
||||||
|
|
||||||
Then edit with your favorite editor. The file is commented and should be
|
|
||||||
self-explanatory.

.TH SNAP-PAC 8 2021-01-29 SNAP-PAC
|
|
||||||
.SH NAME
|
|
||||||
snap-pac \- Pacman hooks that use snapper to create pre/post btrfs snapshots
|
|
||||||
like openSUSE's YaST
|
|
||||||
|
|
||||||
.SH DESCRIPTION
|
|
||||||
|
|
||||||
This is a set of \fIpacman\fR hooks and script that causes \fIsnapper\fR to
|
|
||||||
automatically take a pre and post snapshot before and after pacman transactions,
|
|
||||||
similar to how YaST does with OpenSuse. This provides a simple way to undo
|
|
||||||
changes to a system after a pacman transaction.
|
|
||||||
|
|
||||||
Because these are pacman hooks, it doesn't matter how you call pacman—whether
|
|
||||||
directly, through an AUR helper, or using an alias—snapper will create the
|
|
||||||
snapshots when pacman installs, upgrades, or removes a package. The pacman
|
|
||||||
command used is logged in the snapper description for the snapshots.
|
|
||||||
Additionally the snapshot numbers are output to the screen and to the pacman log
|
|
||||||
for each snapper configuration during the pacman transaction, so that the user can
|
|
||||||
easily find which changes he or she may want to revert.
|
|
||||||
|
|
||||||
To undo changes from a pacman transaction, use \fIsnapper undochange\fR. See
|
|
||||||
\fBsnapper\fR(8) and \fBEXAMPLES\fR.
|
|
||||||
|
|
||||||
If you have severe breakage—like snapper is gone for some reason and you can't
|
|
||||||
get it back—you'll have to resort to more extreme methods, such as taking a
|
|
||||||
snapshot of the pre snapshot and making it the default subvolume or mounting it
|
|
||||||
as \fI/\fR. Most likely you'll need to use a live USB to get into a chroot
|
|
||||||
environment to do any of these things. Snapper has a snapper rollback feature,
|
|
||||||
but your setup has to be properly configured to use it. The exact procedure
|
|
||||||
depends on your specific setup. Be careful.
|
|
||||||
|
|
||||||
.SH CONFIGURATION
|
|
||||||
Configuration is done via Python ini configuration files. The defaults of the
|
|
||||||
should be suitable for most users, so you may not need to do any configuration at all.
|
|
||||||
By default only the "root" snapper configuration is snapshotted.
|
|
||||||
|
|
||||||
A commented example configuration files is located at \fI/etc/snap-pac.ini.example\fR.
|
|
||||||
|
|
||||||
.SH ENVIRONMENT VARIABLES
|
|
||||||
|
|
||||||
To temporarily prevent snapshots from being performed for a single
|
|
||||||
pacman command, set the environment variable \fISNAP_PAC_SKIP\fR. For
|
|
||||||
example:
|
|
||||||
|
|
||||||
.EX
|
|
||||||
|
|
||||||
$ sudo SNAP_PAC_SKIP=y pacman -Syu
|
|
||||||
|
|
||||||
.EE
|
|
||||||
|
|
||||||
|
|
||||||
.SH EXAMPLES
|
|
||||||
|
|
||||||
Here is an example of how the snapshots are created and how to rollback and pacman
|
|
||||||
transaction. Here the \fBnano\fR package is installed:
|
|
||||||
|
|
||||||
.EX
|
|
||||||
|
|
||||||
# pacman -S nano
|
|
||||||

|
|
||||||

|
|
||||||
|
|
||||||
.EE
|
|
||||||
|
|
||||||
The snapper snapshot number is given for each snapper configuration that is
|
|
||||||
used. This is also logged in pacman's log.
|
|
||||||
|
|
||||||
Here are the snapshots created before and after the pacman transaction:
|
|
||||||
|
|
||||||
.EX
|
|
||||||
|
|
||||||
# snapper -c root list -t pre-post | tail -n 1
|
|
||||||
1033 | 1034 | Fri 22 Apr 2016 01:54:13 PM CDT | Fri 22 Apr 2016 01:54:14 PM CDT | pacman -S nano |
|
|
||||||
|
|
||||||
.EE
|
|
||||||
|
|
||||||
Here is what changed during the transaction:
|
|
||||||
|
|
||||||
.EX
|
|
||||||
|
|
||||||
# snapper -c root status 1033..1034
|
|
||||||
+..... /etc/nanorc
|
|
||||||
c..... /etc/snapper/.snap-pac-pre
|
|
||||||
+..... /usr/bin/nano
|
|
||||||
+..... /usr/bin/rnano
|
|
||||||

|

|

+..... /usr/share/doc/nano/fr/nanorc.5.html
|
|
||||||
+..... /usr/share/doc/nano/fr/rnano.1.html
|
|
||||||
|
|
||||||
.EE
|
|
||||||
|
|
||||||
The above output is truncated, but it continues. See the \fBsnapper\fR(8) to
|
|
||||||
for what each symbol means. You can also do \fBsnapper diff\fR in the same way.
|
|
||||||
|
|
||||||
Then, to undo the \fBpacman\fR transaction:
|
|
||||||
|
|
||||||
.EX
|
|
||||||
|
|
||||||
# snapper -c root undochange 1033..1034
|
|
||||||
create:0 modify:3 delete:100
|
|
||||||
|
|
||||||
.EE
|
|
||||||
|
|
||||||
Now nano is no longer installed, along with all the files it changed:
|
|
||||||
|
|
||||||
.EX
|
|
||||||
|
|
||||||
$ pacman -Qi nano
|
|
||||||
error: package 'nano' was not found
|
|
||||||
|
|
||||||
.EE
|
|
||||||
|
|
||||||
.SH TROUBLESHOOTING
|
|
||||||
|
|
||||||
.SS snap-pac is only taking snapshots of the root configuration.
|
|
||||||
That's the default behavior. See \fBCONFIGURATION\fR.
|
|
||||||
|
|
||||||
.SS No snapshots are being taken when I run pacman.
|
|
||||||
No snapper configurations are set up for snap-pac's pacman hooks. By default
|
|
||||||
snap-pac will take snapshots for the root configuration and any other
|
|
||||||
configuration which has SNAPSHOT set to yes in its configuration file.
|
|
||||||
See \fBCONFIGURATION\fR.
|
|
||||||
|
|
||||||
.SS After restoring snapshot from snap-pac, the pacman database is locked.
|
|
||||||
The pre/post snaphots are taken while pacman is running, so this is expected.
|
|
||||||
Follow the instructions pacman gives you (e.g., removing the lock file). You can add the
|
|
||||||
database lock file to a snapper filter so that snapper won't consider it when performing
|
|
||||||
\fBsnapper diff\fR, \fBsnapper status\fR, \fBsnapper undochange\fR, etc. See the
|
|
||||||
\fBFilters\fR section in \fBsnapper\fR(8) for more information.
|
|
||||||
|
|
||||||
|
|
||||||
.SH FAQ
|
|
||||||
.SS Does snap-pac backup non-btrfs /boot partitions?
|
|
||||||
No, but you can add a hook that does it for you. It would be
|
|
||||||
something like the following:
|
|
||||||
|
|
||||||
.EX
|
|
||||||
|
|
||||||
[Trigger]
|
|
||||||
Operation = Upgrade
|
|
||||||
Operation = Install
|
|
||||||
Operation = Remove
|

||||||

|
||||||
Target = linux
|
|
||||||
|
|
||||||
[Action]
|
|
||||||
Description = Backing up /boot...
|
|
||||||
When = PreTransaction
|
|
||||||
Exec = /usr/bin/rsync -avzq --delete /boot /.bootbackup
|
|
||||||
|
|
||||||
.EE
|
|
||||||
|
|
||||||
.SS How do I link old kernel modules automatically when the kernel is upgraded?
|
|
||||||
This behavior is no longer a part of this package. Use a pacman hook like the following:
|
|
||||||
|
|
||||||
[Trigger]
|
|
||||||
Operation = Upgrade
|
