57 | <title>Description</title> | |
58 | ||
59 | <para><filename>systemd-update-done.service</filename> is a | |
60 | service that is invoked as part of the first boot after the vendor | |
61 | operating system resources in <filename>/usr</filename> have been | |
62 | updated. This is useful to implement offline updates of | |
a8eaaee7 | 63 | <filename>/usr</filename> which might require updates to |
798d3a52 ZJS |
64 | <filename>/etc</filename> or <filename>/var</filename> on the |
65 | following boot.</para> | |
66 | ||
67 | <para><filename>systemd-update-done.service</filename> updates the | |
68 | file modification time (mtime) of the stamp files | |
69 | <filename>/etc/.updated</filename> and | |
70 | <filename>/var/.updated</filename> to the modification time of the | |
71 | <filename>/usr</filename> directory, unless the stamp files are | |
72 | already newer.</para> | |
73 | ||
74 | <para>Services that shall run after offline upgrades of | |
75 | <filename>/usr</filename> should order themselves before | |
76 | <filename>systemd-update-done.service</filename>, and use the | |
77 | <varname>ConditionNeedsUpdate=</varname> (see | |
78 | <citerefentry><refentrytitle>systemd.unit</refentrytitle><manvolnum>5</manvolnum></citerefentry>) | |
79 | condition to make sure to run when <filename>/etc</filename> or | |
80 | <filename>/var</filename> are older than <filename>/usr</filename> | |
81 | according to the modification times of the files described above. | |
82 | This requires that updates to <filename>/usr</filename> are always | |
83 | followed by an update of the modification time of | |
84 | <filename>/usr</filename>, for example by invoking | |
85 | <citerefentry project='man-pages'><refentrytitle>touch</refentrytitle><manvolnum>1</manvolnum></citerefentry> | |
86 | on it.</para> | |
