remote-fs.target is ordered after the {auto,}mount units. In case of automount
we do not want to wait for the network to come up before proceeding. In case
of a regular mount unit, the unit will be ordered after network.target
so the behavior is unchanged.
This speeds up boot quite a bit for me when having some services needing
NetworkManager-wait-online.service, and having my home partition on nfs
under an automountpoint.
We don't want to fiddle around changing the RTC, not on bootup, not
on shutdown.
If we don't run NTP, we have absolutely no clue what's the current
time to store in the RTC. If we run NTP, the kernel syncs the system
time every 11 minutes to the RTC.
Especially in multi-boot environents we must not call hwclock(8)
which tries to be smart with calculating/storing/applying drifts
and such.
Live-CDs must never touch the RTC, because we don't know if it is
running in UTC or locatime.
We check for LOCAL in /etc/adjtime and if needed, ask the kernel to
apply the timezone delta to the system clock.
The very first call of settimeofday() without a time, but a timezone
warps the system clock, so that it properly runs in UTC.
Explicitly disconnect all clients from a VT when a getty starts/finishes
(requires TIOCVHANGUP, available in 2.6.29).
Explicitly deallocate getty VTs in order to flush scrollback buffer.
Explicitly reset terminals to a defined state before spawning getty.
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.
Cheers,
Kay
