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><command>systemd-machine-id-commit</command> may be used to
|
|
write on disk any transient machine ID mounted as a temporary file
|
|
system in <filename>/etc/machine-id</filename> at boot time. See
|
|
<citerefentry><refentrytitle>machine-id</refentrytitle><manvolnum>5</manvolnum></citerefentry>
|
|
for more information about this file.</para>
|
|
|
|
<para>This tool will execute no operation if
|
|
<filename>/etc/machine-id</filename> doesn't contain any valid
|
|
machine ID, isn't mounted as an independent temporary file system,
|
|
of <filename>/etc</filename> is read-only. If those conditions are
|
|
met, it will then write current machine ID to disk and unmount the
|
|
transient <filename>/etc/machine-id</filename> file in a race-free
|
|
manner to ensure that this file is always valid for other
|
|
processes.</para>
|
|
|
|
<para>Note that the traditional way to initialize the machine ID
|
|
in <filename>/etc/machine-id</filename> is to use
|
|
<command>systemd-machine-id-setup</command> by system installer
|
|
tools. You can also use
|
|
<citerefentry><refentrytitle>systemd-firstboot</refentrytitle><manvolnum>1</manvolnum></citerefentry>
|
|
to initialize the machine ID on mounted (but not booted) system
|
|
images.</para>
