- GNU GENERAL PUBLIC LICENSE
- Version 2, June 1991
-
- Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
- 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
- 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.
-
- {description}
- 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.
-
- {signature of Ty Coon}, 1 April 1989
- Ty Coon, President of Vice
-
-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.
-
-## Documentation
-
-Run `man 8 snap-pac` after installation.
-
-## Troubleshooting
-
-After reviewing the man page, [check the issues page] and file a new issue if your
-problem is not covered.

-.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
- resolving dependencies...
- looking for conflicting packages...

-
-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
- +..... /usr/share/doc/nano/faq.html
- +..... /usr/share/doc/nano/fr

-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

-
-.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
- Type = Package
- 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
- Operation = Install
- Operation = Remove
- Type = Package
- Target = linux
-
- [Action]
- Description = Symlinking old kernel modules...
- When = PostTransaction
- Exec = /usr/bin/bash -c "find /usr/lib/modules -xtype l -delete; ln -sv /.snapshots/$(snapper -c root list | awk 'END{print $1}')/snapshot/usr/lib/modules/$(uname -r) /usr/lib/modules/"
