systemd-tmpfiles

Proposed hook (systemd)
[Trigger] Type = File Operation = Install Operation = Upgrade Target = usr/lib/tmpfiles.d/*.conf [Action] Description = Creating temporary files... When = PostTransaction Exec = /bin/sh -c 'while read -r f; do /usr/bin/systemd-tmpfiles --create "/$f"; done' NeedsTargets
systemd-sysusers
Used by 29 packages
Proposed hook (systemd)
[Trigger] Type = File Operation = Install Operation = Upgrade Target = usr/lib/sysusers.d/*.conf [Action] Description = Updating system user accounts... When = PostTransaction Exec = /bin/sh -c 'while read -r f; do /usr/bin/systemd-sysusers "/$f" ; done' NeedsTargets
udevadm hwdb, systemd-hwdb
Used by 5 packages
This SHOULD be run with --usr, resulting in /usr/lib/udev/hwdb.bin instead of /etc/udev/hwdb.bin.
Although the latter database overrides the former, this would not be a problem since systemd-hwdb-update.service will update /etc/udev/hwdb.bin at boot if /etc/udev/hwdb.bin exists OR /usr/lib/udev/hwdb.bin does not exist OR /etc/udev/hwdb.d is not empty.
However, this service is also gated on ConditionNeedsUpdate=/etc, which passes if /usr has a newer mtime than /etc/.updated. Unfortunately, ConditionNeedsUpdate (used in quite a few services!) is broken for us since pacman will not update the mtime of directories that already exist, such as /usr.
Proposed hook (systemd)
[Trigger] Type = File Operation = Install Operation = Upgrade Operation = Remove Target = usr/lib/udev/hwdb.d/*.hwdb [Action] Description = Updating udev hardware database... When = PostTransaction Exec = /usr/bin/systemd-hwdb update
fc-cache
Used by 53 packages
Proposed hook (fontconfig)
[Trigger] Type = File Operation = Install Operation = Upgrade Operation = Remove Target = usr/share/fonts/* [Action] Description = Updating fontconfig cache... When = PostTransaction Exec = /usr/bin/fc-cache -s
