In particular, use /lib/systemd instead of /usr/lib/systemd in distributions like Debian which still have not adopted a /usr merge setup. Use XML entities from man/custom-entities.ent to replace configured paths while doing XSLT processing of the original XML files. There was precedent of some files (such as systemd.generator.xml) which were already using this approach. This addresses most of the (manual) fixes from this patch: http://anonscm.debian.org/cgit/pkg-systemd/systemd.git/tree/debian/patches/Fix-paths-in-man-pages.patch?h=experimental-220 The idea of using generic XML entities was presented here: http://lists.freedesktop.org/archives/systemd-devel/2015-May/032240.html This patch solves almost all the issues, with the exception of: - Path to /bin/mount and /bin/umount. - Generic statements about preference of /lib over /etc. These will be handled separately by follow up patches. Tested: - With default configure settings, ran "make install" to two separate directories and compared the output to confirm they matched exactly. - Used a set of configure flags including $CONFFLAGS from Debian: http://anonscm.debian.org/cgit/pkg-systemd/systemd.git/tree/debian/rules Installed the tree and confirmed the paths use /lib/systemd instead of /usr/lib/systemd and that no other unexpected differences exist. - Confirmed that `make distcheck` still passes.

<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 requires 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>
