Since the binary name is now hidden away in /usr/lib/ the primary user
handle for the udev service is the unit name, hence change the man page
to be available under the unit name, and make the binary name an alias
for it.
since the binaries share much of the same code and we better load only
one binary instead of two from disk at early boot let's merge the three
readahead binaries into one. This also allows us to drop a lot of
duplicated code.
TTYVTDisallocate=yes already clears the VT. agetty does not need to do
it again. Run it with --noclear.
Felix Miata found the double clearing confusing in this bugreport:
https://bugzilla.redhat.com/show_bug.cgi?id=828007
Add a comment explaining what clears the VT.
In rescue mode let's not establish all sockets, so that we don't end up
starting a lot of additional services automatically.
Instead of pulling in basic.target we now only pull in sysinit.target
which pulls in local-fs.target and swap.target. That way rescue mode has
all the really basic setup around, but normal services are not started
and not autostarted either.
This should help making the boot process a bit easier to explore and
understand for the administrator. The simple idea is that "systemctl
status" now shows a link to documentation alongside the other status and
decriptionary information of a service.
This patch adds the necessary fields to all our shipped units if we have
proper documentation for them.
RequiresMountsFor= is a shortcut for adding requires and after
dependencies to all mount units neeed for the specified paths.
This solves a couple of issues regarding dep loop cycles for encrypted
swap.
We shouldn't hardcode the name of the NTP implementation in the
timedated mechanism, especially since Fedora currently switched from NTP
to chrony.
This patch introduces a new target that is enabled/disabled instead of
the actual NTP implementation. The various NTP implementations should
then add .wants/ symlinks to their services and BindTo back to the
target, so that their implementations are started/stopped jointly with
the target.

Type=idle is much like Type=simple, however between the fork() and the
exec() in the child we wait until PID 1 informs us that no jobs are
left.
This is mostly a cosmetic fix to make gettys appear only after all boot
output is finished and complete.
Note that this does not impact the normal job logic as we do not delay
the completion of any jobs. We just delay the invocation of the actual
binary, and only for services that otherwise would be of Type=simple.
We finally got the OK from all contributors with non-trivial commits to
relicense systemd from GPL2+ to LGPL2.1+.
Some udev bits continue to be GPL2+ for now, but we are looking into
relicensing them too, to allow free copy/paste of all code within
systemd.
The bits that used to be MIT continue to be MIT.
The big benefit of the relicensing is that closed source code may now
link against libsystemd-login.so and friends.
gettys are nowadays mostly autospawned and hence usually subject to
being shut down on isolate requests, since they are no dependency of any
other unit. This is a bad idea if the user isolates between
multi-user.graphical and graphical.target, hence exclude them from the
isolation.
This has the effect that gettys no longer cleaned up when
emergency.target is isolated, which might actualy be considered a
feature, even though it is a change from previous behaviour...
Note that the one getty that really matters (the one on tty1) is still
removed when isolating to emergency.target since it conflicts with
emergency.service.
This separates user/group NSS lookups from host/network NSS lookups.
By default order all network mounts after host/network NSS lookups now,
and logind execution after user/group NSS lookups.
Especially in the case of --enable-split-usr, several units will point
to the wrong location for systemctl. Use @SYSTEMCTL@ which will always
contain the proper path.
The default setups should be a stateless as possible. /tmp as tmpfs is
the intended default for general purpose systems.
Small temporary files should not be stored on disk; lager files, or
files which should potentially survive a reboot, belong into /var/tmp.
Also catch up with some good old UNIX history.
More details are here:
https://fedoraproject.org/wiki/Features/tmp-on-tmpfs
Since a number of distribitions don't need this compat glue anymore drop
it from systemd upstream. Distributions which still haven't converted
to /run can steal these unit files from the git history if they need to.
udisks2 doesn't use /media anymore, instead mounts removable media in a
user-private directory beneath /run. /media is hence mostly obsolete and
hence it makes little sense to continue to mount a tmpfs to it.
Distributions should consider dropping the mount point entirely since
nothing uses it anymore.
This is an S/MIME signed message
The mount of the securityfs filesystem is now performed in the main systemd
executable as it is used by IMA to provide the interface for loading custom
policies. The unit file 'units/sys-kernel-security.mount' has been removed
because it is not longer necessary.

rc-local.service acts as an ordering barrier even if its condition is
false, because conditions are evaluated when the service is about to be
started.
To avoid the ordering barrier in a legacy-free system, add a generator
to pull rc-local.service into the transaction only if the script is
executable.
If/when we rewrite SysV compatibility into a generator, this one can become
a part of it.
Both kmsg-syslogd and the real syslog service want to receive
SCM_CREDENTIALS. With socket activation it is too late to set
SO_PASSCRED in the services.
Since Linux 3.2 in order to receive SCM_CREDENTIALS it is not sufficient
to set SO_PASSCRED just before recvmsg(). The option has to be already
set when the sender sends the message.
With socket activation it is too late to set the option in the service.
It must be set on the socket right from the start.
See the kernel commit:
16e57262 af_unix: dont send SCM_CREDENTIALS by default
Fixes: https://bugzilla.redhat.com/show_bug.cgi?id=757628
DefaultStandardOutput is syslog anyway. There's no reason to assume that
the administrator would want these units to be excluded when he configures
a different DefaultStandardOutput.
This patch adds support for the Mageia Linux distribution:
http://www.mageia.org/
Mageia is a fork of Mandriva although some divergence has already occured
and thus inclusion of these changes upstream allow us to (hopefully)
migrate more rapidly to the new standard approaches systemd offers.
Indeed, we already use the preferred mechanism of OS identification via
the /etc/os-release file rather than a distro specific variation.
This patch mostly mirrors the patch added previously for Mandriva
support. In addition to those original authors, this patch was mostly
written by Dexter Morgan with help from Colin Guthrie and Eugeni Dodonov.
In order to ensure that bind mounts copy the final mount settings to the
new bind mount make the root and API FS mount options are applied before
the other file systems are mounted.

It was possible for the "ExecStartPre=-/bin/plymouth quit" to race
with plymouth-start.service which is pulled in indirectly by
basic.target -> sysinit.target.
The race left plymouth running on the terminal, making it unusable for
rescue purposes.
https://bugzilla.redhat.com/show_bug.cgi?id=710487
The mount point directory /sys/kernel/config is only created after the
module is loaded, hence there's little value in having this an automount
unit: the runtime penalty for mounting an autofs here should be the same
as for a real mount.
With output of services going to syslog by default now, the rescue shell
units need to direct their output to tty explicitly.
Specify stderr too, just in case.
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
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
