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-debug-generator</filename> is a generator
|
|
that reads the kernel command line and understands three
|
|
options:</para>
|
|
|
|
<para>If the <option>systemd.mask=</option> option is specified
|
|
and followed by a unit name, this unit is masked for the runtime,
|
|
similar to the effect of
|
|
<citerefentry><refentrytitle>systemctl</refentrytitle><manvolnum>1</manvolnum></citerefentry>'s
|
|
<command>mask</command> command. This is useful to boot with
|
|
certain units removed from the initial boot transaction for
|
|
debugging system startup. May be specified more than once.</para>
|
|
|
|
<para>If the <option>systemd.wants=</option> option is specified
|
|
and followed by a unit name, a start job for this unit is added to
|
|
the initial transaction. This is useful to start one or more
|
|
additional units at boot. May be specified more than once.</para>
|
|
|
|
<para>If the <option>systemd.debug-shell</option> option is
|
|
specified, the debug shell service
|
|
<literal>debug-shell.service</literal> is pulled into the boot
|
|
transaction. It will spawn a debug shell on tty9 during early
|
|
system startup. Note that the shell may also be turned on
|
|
persistently by enabling it with
|
|
<citerefentry><refentrytitle>systemctl</refentrytitle><manvolnum>1</manvolnum></citerefentry>'s
|
|
<command>enable</command> command.</para>
|
|
|
|
<para><filename>systemd-debug-generator</filename> implements
|
|
<citerefentry><refentrytitle>systemd.generator</refentrytitle><manvolnum>7</manvolnum></citerefentry>.</para>
