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>kernel-install</command> is used to install and remove kernel and
|
|
initramfs images to and from <filename>/boot</filename>.
|
|
</para>
|
|
|
|
<para><command>kernel-install</command> will execute the files
|
|
located in the directory <filename>/usr/lib/kernel/install.d/</filename>
|
|
and the local administration directory <filename>/etc/kernel/install.d/</filename>.
|
|
All files are collectively sorted and executed in lexical order, regardless of the directory in
|
|
which they live. However, files with identical filenames replace each other.
|
|
Files in <filename>/etc/kernel/install.d/</filename> take precedence over files with the same name
|
|
in <filename>/usr/lib/kernel/install.d/</filename>. This can be used to override a system-supplied
|
|
executables with a local file if needed; a symbolic link in <filename>/etc/kernel/install.d/</filename>
|
|
with the same name as an executable in <filename>/usr/lib/kernel/install.d/</filename>,
|
|
pointing to /dev/null, disables the executable entirely. Executables must have the
|
|
extension <literal>.install</literal>; other extensions are ignored.</para>

<replaceable>KERNEL-IMAGE</replaceable> to

It also creates a boot loader entry according to the boot

loader specification in

<filename>/boot/loader/entries/<replaceable>MACHINE-ID</replaceable>-<replaceable>KERNEL-VERSION</replaceable>.conf</filename>.

The title of the entry is the

in <filename>/etc/os-release</filename> or

<filename>/usr/lib/os-release</filename> (if the former is

|
missing), or "Linux

|
<replaceable>KERNEL-VERSION</replaceable>", if unset. If
|
|
the file <filename>initrd</filename> is found next to the
|
|
<filename>linux</filename> file, the initrd will be added to
|
|
the configuration.</para>
