systemd-update-done.service, systemd-update-done - Mark /etc and /var
fully updated
systemd-update-done.service
/usr/lib/systemd/systemd-update-done
systemd-update-done.service is a service that is invoked as part of
the first boot after the vendor operating system resources in /usr
have been updated. This is useful to implement offline updates of
/usr which might require updates to /etc or /var on the following
boot.
systemd-update-done.service updates the file modification time
(mtime) of the stamp files /etc/.updated and /var/.updated to the
modification time of the /usr directory, unless the stamp files are
already newer.
Services that shall run after offline upgrades of /usr should order
themselves before systemd-update-done.service, and use the
ConditionNeedsUpdate= (see systemd.unit(5)) condition to make sure to
run when /etc or /var are older than /usr according to the
modification times of the files described above. This requires that
updates to /usr are always followed by an update of the modification
time of /usr, for example by invoking touch(1) on it.
