StatusErrno dbus property along StatusText to allow notification of numeric status condition while degraded service operation or any other special situation.

or when creating OS images offline
A new tool "systemd-firstboot" can be used either interactively on boot,
where it will query basic locale, timezone, hostname, root password
information and set it. Or it can be used non-interactively from the
command line when prepareing disk images for booting. When used
non-inertactively the tool can either copy settings from the host, or
take settings on the command line.
$ systemd-firstboot --root=/path/to/my/new/root --copy-locale --copy-root-password --hostname=waldi
The tool will be automatically invoked (interactively) now on first boot
if /etc is found unpopulated.
This also creates the infrastructure for generators to be notified via
an environment variable whether they are running on the first boot, or
not.

Previously, we checked whether /etc was completely empty. This makes it
difficult though for container managers such as nspawn to install a
small number of files (such as /etc/timezone), and have the system
otherwise populate its own tree.
Hence, change this by looking for /etc/machine-id, which should be a
good sign whether /etc is populated or not.

We should follow the naming scheme waitid() uses, not come up with our
own reversed one...

This does the inverse of RestartPreventExitStatus=: it forces a restart
of a service when a certain exit status is returned by a service
process.

Instead of adjusting job timeouts in the core, let fstab-generator
write out a dropin snippet with the appropriate JobTimeout.
x-systemd-device.timeout option is removed from Options= line
in the generated unit.
The functions to write dropins are moved from core/unit.c to
shared/dropin.c, to make them available outside of core.
generator.c is moved to libsystemd-label, because it now uses
functions defined in dropin.c, which are in libsystemd-label.

There's little reason to export this, so let's drop it to minimize the
file a bit.

This is useful for code that tries to figure out the primary arch's
$libdir on the local system, given that is different on the various
Linuxes.

The stamp file for systemd --user timers was named stamp-foo.timer if
XDG_DATA_HOME was unset, but foo.timer otherwise.

Patch fixes some incorrect-looking code in transaction.c.
It could fix cases where Debian users with bad package configurations
had systemd go into an infinite loop printing messages about breaking an
ordering cycle, though I have not reproduced that problem myself.
transaction_verify_order_one() considers jobs/units outside current
transaction when checking whether ordering dependencies cause cycles.
It would also incorrectly try to break cycles at these jobs; this
cannot work, as the break action is to remove the job from the
transaction, which is a no-op if the job isn't part of the transaction
to begin with. The unit_matters_to_anchor() test also looks like it
would not work correctly for non-transaction jobs. Add a check to
verify that the unit is part of the transaction before considering a
job a candidate for deletion.

Failure to mount cgroups with xattr should not be fatal

When running in 'quiet' mode, the only message printed from shutdown
binary would be 'Cannot finalize remaining file systems and devices,
giving up.', the only log line at error level before switch back to
initramfs. This is misleading, because in initramfs everything will
be cleaned up properly.
Avoid printing anything at error level before the attempt to switch
back to initramfs. Rework the messages to contain a bit more
information what is still remaining, to help people diagnose shutdown
issues.

This allows us to bootup a rootfs with a /usr directory only.

Snapshot mechanism is not used very much, but snapshot creation/destruction
should be at least as verbose as normal unit starting/stopping.

There's no point in telling the user to look at the logs when
an attempt to load the unit file failed with ENOENT.

There's no need to save the old sigmask, if we are going to die. Let's
simplify this. Also, reset all the signal handlers, so that we don't
leave SIG_IGN set for some of them across reexec.

value starting with "systemd."
As generators and other components started to maintain their own kernel
command line options this help text needed more and more exceptions and
wasn't complete anyway. Fixing that would leak more information about
specific generators into PID 1, which we should avoid.
Given that kernel cmdline handling traditionally doesn't generate errors
or show help texts, let's just remove the logic for it for systemd too.

It's generally preferrable to conditionalize on the actual ability to do

"debug" should apply to all tools, but "quiet" only to PID1.

The DefaultInstance= name is used when enabling template units when only
specifying the template name, but no instance.
Add DefaultInstance=tty1 to getty@.service, so that when the template
itself is enabled an instance for tty1 is created.
This is useful so that we "systemctl preset-all" can work properly,
because we can operate on getty@.service after finding it, and the right
instance is created.

do all-unit preset operations
The new "systemctl preset-all" command may now be used to put all
installed units back into the enable/disable state the vendor/admin
encoded in preset files.
Also, introduce "systemctl --preset-mode=enable-only" and "systemctl
--preset-mode=disable-only" to only apply the enable or only the disable
operations of a "systemctl preset" or "systemctl preset-all" operation.
"systemctl preset-all" implements this RFE:

Process 1 (aka init) needs to be started with an empty signal mask.
That includes the process 1 that's started after the initrd is finished.
When the initrd is using systemd (as it does with dracut based initrds)
then it is systemd that calls the real init. Normally this is systemd
again, except when the user uses for instance "init=/bin/bash" on the
kernel command line.

/etc/mtab should die die die. It's sad enough util-linux still contains
support for it, but we don't have to partake in that charade, so let's
turn this off.
This is in-line with the fact that since years we already have been
"tainting" systemd if we detect /etc/mtab not being a symlink...
Of course, util-linux is currently broken, and still touches /etc/mtab,
weven if we pass "--no-mtab" to it:
https://bugzilla.redhat.com/show_bug.cgi?id=1109367
But hey, let's hope that gets fixed quickly, even if total removal of
/etc/mtab support from util-linux might not happen so quickly...
|
|
When we boot up with an empty /etc it's ok if the symlink doesn't exist.
We will create it later with tmpfiles.
|
|
The file should have been in /usr/lib/ in the first place, since it
describes the OS container in /usr (and not the configuration in /etc),
hence, let's support os-release files in /usr/lib as fallback if no
version in /etc exists, following the usual override logic.
A prior commit already enabled tmpfiles to create /etc/os-release as a
symlink to /usr/lib/os-release should it be missing, thus providing nice
compatibility with applications only checking in /etc.
While it's probably a good idea if all apps check both locations via a
fallback logic, it is only necessary in the early boot process, as long
as the /etc/os-release symlink has not been restored, in case we boot
with an empty /etc.

With this in place RPMs can make sure that whatever they drop in is
immeidately applied, and not delayed until next reboot.
This also moves systemd-sysusers back to /usr/bin, since hardcoding the
path to /usr/lib in the macros would mean compatibility breaks in
future, should we turn sysusers into a command that is actually OK for
people to call directly. And given that that is quite likely to happen
(since it is useful to prepare images with its --root= switch), let's
just prepare for it.
|
|
this gives us a little bit more freedom to move things around later on,
as we don't hardcode the systemd paths in old RPMs that shall work with
new systemds.
