<title>Description</title>
|
|
|
|
<para><filename>systemd-update-done.service</filename> is a
|
|
service that is invoked as part of the first boot after the vendor
|
|
operating system resources in <filename>/usr/</filename> have been
|
|
updated. This is useful to implement offline updates of
|
|
<filename>/usr/</filename> which might require updates to
|
|
<filename>/etc/</filename> or <filename>/var/</filename> on the
|
|
following boot.</para>
|
|
|
|
<para><filename>systemd-update-done.service</filename> updates the
|
|
file modification time (mtime) of the stamp files
|
|
<filename>/etc/.updated</filename> and
|
|
<filename>/var/.updated</filename> to the modification time of the
|
|
<filename>/usr/</filename> directory, unless the stamp files are
|
|
already newer.</para>
|
|
|
|
<para>Services that shall run after offline upgrades of
|
|
<filename>/usr/</filename> should order themselves before
|
|
<filename>systemd-update-done.service</filename>, and use the
|
|
<varname>ConditionNeedsUpdate=</varname> (see
|
|
<citerefentry><refentrytitle>systemd.unit</refentrytitle><manvolnum>5</manvolnum></citerefentry>)
|
|
condition to make sure to run when <filename>/etc/</filename> or
|
|
<filename>/var/</filename> are older than <filename>/usr/</filename>
|
|
according to the modification times of the files described above.
|
|
This requires that updates to <filename>/usr/</filename> are always
|
|
followed by an update of the modification time of
|
|
<filename>/usr/</filename>, for example by invoking
|
|
<citerefentry project='man-pages'><refentrytitle>touch</refentrytitle><manvolnum>1</manvolnum></citerefentry>
|
|
on it.</para>
|
|
|
|
<para>Note that if the <varname>systemd.condition-needs-update=</varname> kernel command line option is
|
|
used it overrides the <varname>ConditionNeedsUpdate=</varname> unit condition checks. In that case
|
|
<filename>systemd-update-done.service</filename> will not reset the condition state until a follow-up
|
|
reboot where the kernel switch is not specified anymore.</para>
