pacman-sync

script and hook for usage with pacman to synchronize directories that were updated during a system upgrade

Usage

Install as pacman/libalpm hook.

$ python3 sync_fs.py -h
usage: sync_fs.py [-h] [-d]

Script for syncing mountpoints after system upgrades, to be used as script for an alpm-hook

options:
  -h, --help   show this help message and exit
  -d, --debug  Enable debug mode

Internals

It finds the mountpoints that were changed by the installation/removal/upgrade of packages and syncs them to make sure the changes were written to disk before you continue using the system. This makes sure that if something bad happens afterwards that kills the system, the files that were changed by the package upgrade are already on the disk and can be used to start the system again.

To do this it does these things:

get all mounts on the system
remove all mounts of types that are in memory
remove all overlay filesystems
reads in each line of stdin (this is how pacman/libalpm integrate these hooks)
for each line it read from stdin, it finds on which of the remaining mounts it is and adds that mount to a list unless it is already on there
it syncs all mounts that are in the list

Testing

You can easily test the script like this:

cat <<EOF | python3 sync_fs.py
/
/usr/share/test
/usr/share
/mnt/other/foo
/mnt/other/foobar
/mnt/other/test1
/sys/foo
/sys/foo/bar
/proc/123
/proc123123
/dev/pts/foo
/dev/foo
/dev
EOF

It will then output something like this:

2024-05-24 04:42:57,777 - INFO: Syncing these mountpoints now: ['/', '/mnt/other']
2024-05-24 04:42:57,778 - INFO: Mountpoints now synced

With debug mode activated you can see what it does internally:
