This did not really work out as we had hoped. Trying to do this upstream
introduced several problems that probably makes it better suited as a
downstream patch after all. At any rate, it is not releaseable in the
current state, so we at least need to revert this before the release.
* by adjusting the path to binaries, but not do the same thing to the
search path we end up with inconsistent man-pages. Adjusting the search
path too would be quite messy, and it is not at all obvious that this is
worth the effort, but at any rate it would have to be done before we
could ship this.
* this means that distributed man-pages does not make sense as they depend
on config options, and for better or worse we are still distributing
man pages, so that is something that definitely needs sorting out before
we could ship with this patch.
* we have long held that split-usr is only minimally supported in order
to boot, and something we hope will eventually go away. So before we start
adding even more magic/effort in order to make this work nicely, we should
probably question if it makes sense at all.
./configure --enable/disable-kdbus can be used to set the default
behavior regarding kdbus.
If no kdbus kernel support is available, dbus-dameon will be used.
With --enable-kdbus, the kernel command line option "kdbus=0" can
be used to disable kdbus.
With --disable-kdbus, the kernel command line option "kdbus=1" is
required to enable kdbus support.
This adds man-pages for most of the libudev symbols we export. Similar
symbols are grouped together in a single man-page, with respective links
added. All man-pages contain the full skeleton including NAME, SYNOPSIS,
RETURN VALUE and SEE ALSO. However, most of them still lack the
DESCRIPTION part. This should be copied from the gtkdoc descriptions in
src/libudev/libudev*.[ch]. Any help is welcome! (the whole skeleton is
already done, so it's really just about the prose-part of the man-pages to
be written).
Missing from the man-pages are the following parts:
- udev_set_log_fn()
- udev_[gs]et_log_priority()
- udev_[gs]et_userdata()
- udev_list_entry_foreach()
- udev_device_get_seqnum()
- udev_device_get_usec_since_initialized()
- udev_util_encode_string()
These are considered legacy, afaik. If not, please feel free to add them
now!
Furthermore, udev-hwdb and udev-queue are not documented at all (for the
same reasons).
We do not support '/run' for hwdb files. Drop it from the man-pages so
people don't accidentally use it.

Improve the documentation of bus credentials by mentioning send-time metadata. This needs more love, we should really clarify metadata details here. However, this is still better than nothing, so it's fine.
Two of the bits in the MAC address are set unconditioanlly, and the rest is randomized,
make this clear in the documentation (as it currently read as if it was all random).
If the EDITOR environment variable is not set, the Debian policy
recommends to use the /usr/bin/editor program as default editor.
This file is managed via the dpkg alternatives mechanism and typically
used in Debian/Ubuntu and derivatives to configure the default editor.
See section 11.4 of the Debian policy [1].
Therefor prefer /usr/bin/editor over specific editors if available.

Export the MOUNT_PATH and UMOUNT_PATH variables as XML entities and use them in
the systemctl.1 manpage instead of hardcoding the path in /usr/bin.
Tested:
- Ran ./configure ac_cv_path_MOUNT_PATH=/bin/mount (same for umount) and
rebuilt the manpages, confirmed that the correct path was in man/systemctl.1
- Rebuilt man/systemd.directives.xml and the man pages derived from it,
confirmed that the correct paths were there as well.
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.
This patch simplify swapon usage in systemd. The command swapon(8)
since util-linux v2.26 supports "-o <list>". The idea is exactly the
same like for mount(8). The -o specifies options in fstab-compatible
way. For systemd it means that it does not have to care about things
like "discard" or another swapon specific options.
swapon -o <options-from-fstab>
For backward compatibility the code cares about "Priority:" swap unit
field (for a case when Priority: is set, but pri= in the Options: is
missing).

The hostname(1) tool allows comments in /etc/hostname. Introduce a new
read_hostname_config() in hostname-util which reads a hostname configuration
file like /etc/hostname, strips out comments, whitespace, and cleans the
hostname. Use it in hostname-setup.c and hostnamed and remove duplicated code.
Update hostname manpage. Add tests.

Currently we have no way how to specify dependencies between fstab
entries (or another units) in the /etc/fstab. It means that users are
forced to bypass fstab and write .mount units manually.
The patch introduces new systemd fstab options:
x-systemd.requires=<PATH>
- to specify dependence an another mount (PATH is translated to unit name)
x-systemd.requires=<UNIT>
- to specify dependence on arbitrary UNIT
x-systemd.requires-mounts-for=<PATH ...>
- to specify dependence on another paths, implemented by
RequiresMountsFor=. The option may be specified more than once.
For example two bind mounts where B depends on A:
/mnt/test/A /mnt/test/A none bind,defaults
/mnt/test/A /mnt/test/B none bind,x-systemd.requires=/mnt/test/A
More complex example with overlay FS where one mount point depends on
"low" and "upper" directories:
/dev/sdc1 /mnt/low ext4 defaults
/dev/sdc2 /mnt/high ext4 defaults
overlay /mnt/merged overlay lowerdir=/mnt/low,upperdir=/mnt/high/data,workdir=/mnt/high/work,x-systemd.requires-mounts-for=/mnt/low,x-systemd.requires-mounts-for=mnt/high
