These lines are generally out-of-date, incomplete and unnecessary. With SPDX and git repository much more accurate and fine grained information about licensing and authorship is available, hence let's drop the per-file copyright notice. Of course, removing copyright lines of others is problematic, hence this commit only removes my own lines and leaves all others untouched. It might be nicer if sooner or later those could go away too, making git the only and accurate source of authorship information.

<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>
