The rule is that units that encapsulate our own code are prefixed with
"systemd-". Since the fsck units invoke our own code, hence add the
missing prefix. Since a long long time the fsck units didn't invoke the
naked fsck binaries anymore, and it is unlikely that this well ever
change. On the opposite: the code in systemd-fsck will probably get more
complex over time to handle fsck progress to plymouth forwarding.
Same for quotacheck (but not quotaon!)
Names= is a source of errors, simply because alias names specified like
this only become relevant after a unit has been loaded but cannot be
used to load a unit.
Let's get rid of the confusion and drop this field. To establish alias
names peope should use symlinks, which have the the benefit of being
useful as key to load a unit, even though they are not taken into
account if unit names are listed but they haven't been explicitly
referenced before.
People should use systemd.pc if anything at all to determine these
directories, and people should not assume that the bus fields are part
of the supported API, so let's just drop this.
This option never made much sense. It was originally intended to make
sure that the usual startup output of sysv scripts goes to the terminal.
However, since SysV scripts started from a terminal would not output to
that terminal, but rather /dev/console this effect was more often than
not actually taking place. Nowadays systemd has much nicer boot time
status output than SysV which makes the sysv output redundant. Finally,
all output of services goes to the journal anyway, and is not lost.
Hence, let's drop this option, and simplify things a bit.
This makes sure that
systemctl status /home
is implicitly translated to:
systemctl status /home.mount
Similar, /dev/foobar becomes dev-foobar.device.
Also, all characters that cannot be part of a unit name are implicitly
escaped.
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.
As described in
https://bugs.freedesktop.org/show_bug.cgi?id=50184
the journal currently doesn't set fields such as _SYSTEMD_UNIT
properly for messages coming from processes that have already
terminated. This means among other things that "systemctl status" may
not show some of the output of services that wrote messages just
before they exited.
This patch fixes this by having processes that log to the journal
write their unit identifier to journald when the connection to
/run/systemd/journal/stdout is opened. Journald stores the unit ID
and uses it to fill in _SYSTEMD_UNIT when it cannot be obtained
normally (i.e. from the cgroup). To prevent impersonating another
unit, this information is only used when the caller is root.
This doesn't fix the general problem of getting metadata about
messages from terminated processes (which requires some kernel
support), but it allows "systemctl status" and similar queries to do
the Right Thing for units that log via stdout/stderr.
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.
Let's try to standardize a bit the RPM macros used for
installing/uninstalling services.
This only covers the non-SysV compat bits, since that tends to vary
widely between the various distros.
Usage:
Add %{?systemd_requires} to the header of the spec file. And then:
%post
%systemd_post foobar.service
%preun
%systemd_preun foobar.service
%postun
%systemd_postun foobar.service
And, instead of the latter, in case the service shall be restarted on updates:
%postun
%systemd_postun_restart foobar.service
online = logged in
active = logged in and session is in the fg
closing = nominally logged out but some left-over processes still around

Since we boot so fast now that gdm might get started before the
graphics drivers are properly loaded and probed we might end up
announcing seat0 to gdm before it has graphics capabilities. Which will
cause gdm/X11 cause to fail later on.
To fix this race, let's expose CanGraphical and CanTTY fields on all
seats, which clarify whether a seat is suitable for gdm resp, suitable
for text logins. gdm then needs to watch CanGraphical and spawn X11 on
it only if it is true.
This way:
USB graphics seats will expose CanGraphical=yes, CanTTY=no
Machines with no graphics drivers at all, but a text console:
CanGraphical=no, CanTTY=yes
Machines with CONFIG_VT turned off: CanGraphical=yes, CanTTY=no
And the most important case: seat0 where the graphics driver has not
been probed yet boot up with CanGraphical=no, CanTTY=yes first, which
then changes to CanGraphical=yes as soon as the probing is complete.
The sssd folks would like to place the kerberos credential cache in
XDG_RUNTIME_DIR, but need to do that in the PAM auth hooks, before
pam_systemd is run as part of the PAM session setup. Hence, in order to
make this easy for them: avoid usage of usernames, and use user IDs
instead thus making an additional NSS lookup unnecessary in the kerberos
bits, but still have the directory well-defined so that the kerberos
bits can determine it before pam_systemd is run.
