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.

<para>If invoked with no arguments, it applies all directives from

all configuration files. If one or more filenames are passed on

the command line, only the directives in these files are applied.

If only the basename of a configuration file is specified, all

configuration directories as specified in
|

<citerefentry><refentrytitle>tmpfiles.d</refentrytitle><manvolnum>5</manvolnum></citerefentry>

<para>It is possible to combine <option>--create</option>,

invocation. For example, during boot the following command line is

executed to ensure that all temporary and volatile directories are

removed and created according to the configuration file:</para>

<title>Unprivileged --cleanup operation</title>

|
|
<para><command>systemd-tmpfiles</command> tries to avoid changing

|
the access and modification times on the directories it accesses,
|
|
which requires <constant>CAP_ADMIN</constant> privileges. When
|
|
running as non-root, directories which are checked for files to
|
|
clean up will have their access time bumped, which might prevent
|
|
their cleanup.
