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 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.
Note that if the systemd.condition-needs-update= kernel command line
option is used it overrides the ConditionNeedsUpdate= unit condition
checks. In that case systemd-update-done.service will not reset the
condition state until a follow-up reboot where the kernel switch is not
specified anymore.
