SYSTEMD-UPDATE-DONE.SERVICE(8) systemd-update-done.service SYSTEMD-UPDATE-DONE.SERVICE(8)
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.
