NAME
       systemd-update-done.service, systemd-update-done - Mark /etc and /var fully updated

SYNOPSIS
       systemd-update-done.service

       /usr/lib/systemd/systemd-update-done

DESCRIPTION
       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 requires 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.
