This commit consists of the initial work to include MeeGo as a ported
distribution for systemd.
The majority of the changes are small configuration additions to auto
tools, so that MeeGo is identified as a valid distribution option.
Some small deviations will be noticed between the configuration of MeeGo
and other distributions. As MeeGo is a distribution striving for
compliancy to support its near embedded attributes and target users,
there is less user configuration options available by default. Most
services will be enabled by systemd as part of the distribution
requirements, and as such most links and service files will be pre-setup
for the MeeGo distribution. As much of this is going to be done within
the MeeGo distribution packaging this is still noteworthy to mention, as
it explains why in systemd you will observe configuration differences
where the MeeGo distribution removes all links in the pkgsysconfdir for
instance. MeeGo will be user configurable if there is desire, but most
services will be enabled by the distribution as designated by the MeeGo
compliancy standards.
Other changes are in source to add such areas as meego-release defined
in utils, and hostname in hostname-setup, defining vconsole-setup,
localizations and rescue additions as needed.
As this is all ground work, MeeGo will continue to strive for complete
compatibility.
On request of Miroslav Lichvar, rename rtc-set.target to
time-sync.target since usually the RTC chip isn't involved at all in NTP
syncs.
Also, pull it in by hwclock-load.service.

systemd now watches /run/initramfs/plymouth and generates messages
exactly when that file exists. Hence we don't need the sending of the
signals anymore.
Instead of the /dev/.run trick we have currently implemented, we decided
to move the early-boot runtime dir to /run.
An existing /var/run directory is bind-mounted to /run. If /var/run is
already a symlink, no action is taken.
An existing /var/lock directory is bind-mounted to /run/lock.
If /var/lock is already a symlink, no action is taken.
To implement the directory vs. symlink logic, we have a:
ConditionPathIsDirectory=
now, which is used in the mount units.
Skipped mount unit in case of symlink:
$ systemctl status var-run.mount
var-run.mount - Runtime Directory
Loaded: loaded (/lib/systemd/system/var-run.mount)
Active: inactive (dead)
start condition failed at Fri, 25 Mar 2011 04:51:41 +0100; 6min ago
Where: /var/run
What: /run
CGroup: name=systemd:/system/var-run.mount
The systemd rpm needs to make sure to add something like:
%pre
mkdir -p -m0755 /run >/dev/null 2>&1 || :
or it needs to be added to filesystem.rpm.
Udev -git already uses /run if that exists, and is writable at bootup.
Otherwise it falls back to the current /dev/.udev.
Dracut and plymouth need to be adopted to switch from /dev/.run to run
too.

Now that we have /dev/.run there's no need to use abstract namespace
sockets. So, let's move things to /dev/.run, to make things more easily
discoverable and improve compat with chroot() and fs namespacing.
During early boot, mount a tmpfs to /dev/.run and then bind mount it to
/var/run as soon as /var is available.
This makes it possible for programs involved in early boot to put
runtime data in /dev/.run which later on will show up in /var/run like
any other.
This can be used to solve the early-boot D-Bus problem: D-Bus may start
up with its socket bound to /dev/.run/dbus/system_bus_socket and after
/var it will also be available under the traditional name
/var/run/dbus/system_bus_socket.
This also is intended to be used as a better place for systemd, mount,
mdadm, blkid, plymouth, bootchart and dracut runtime data, which is
currently stored in various places in /dev/.xxx.
This merges several separate patches that I carry as part of
Mandriva systemd RPM. They touch those parts that are very
unlikely to be changed in near future and do not impose any
functionality change for systemd core. I also think it is
useful for troubleshooting to have real distribution name in
system logs, espicially when someone reports problem upstream.
The patch looks bigger than sum of replaced patches because
- previous patches were applied on top of distro=fedora, now
I need to add all those bits for distro=mandriva as well
- part of patch was done as spec file magic, but it seems more
logical to ship all these bits together
