30 | <title>Description</title> | |
31 | ||
32 | <para><filename>systemd-update-done.service</filename> is a | |
33 | service that is invoked as part of the first boot after the vendor | |
34 | operating system resources in <filename>/usr</filename> have been | |
35 | updated. This is useful to implement offline updates of | |
a8eaaee7 | 36 | <filename>/usr</filename> which might require updates to |
798d3a52 ZJS |
37 | <filename>/etc</filename> or <filename>/var</filename> on the |
38 | following boot.</para> | |
39 | ||
40 | <para><filename>systemd-update-done.service</filename> updates the | |
41 | file modification time (mtime) of the stamp files | |
42 | <filename>/etc/.updated</filename> and | |
43 | <filename>/var/.updated</filename> to the modification time of the | |
44 | <filename>/usr</filename> directory, unless the stamp files are | |
45 | already newer.</para> | |
46 | ||
47 | <para>Services that shall run after offline upgrades of | |
48 | <filename>/usr</filename> should order themselves before | |
49 | <filename>systemd-update-done.service</filename>, and use the | |
50 | <varname>ConditionNeedsUpdate=</varname> (see | |
51 | <citerefentry><refentrytitle>systemd.unit</refentrytitle><manvolnum>5</manvolnum></citerefentry>) | |
52 | condition to make sure to run when <filename>/etc</filename> or | |
53 | <filename>/var</filename> are older than <filename>/usr</filename> | |
54 | according to the modification times of the files described above. | |
55 | This requires that updates to <filename>/usr</filename> are always | |
56 | followed by an update of the modification time of | |
57 | <filename>/usr</filename>, for example by invoking | |
58 | <citerefentry project='man-pages'><refentrytitle>touch</refentrytitle><manvolnum>1</manvolnum></citerefentry> | |
59 | on it.</para> | |
