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.
Rather than assuming the console is in utf-8 mode if nothing else is
specified, be a bit more robust and enable it explicitly.
This fixes a regression compared with Arch's initscripts when not
using a framebuffer as the old VGA console would not be in utf-8
mode by default.
Furthermore, this would allow vconsole-setup to be used after boot
to change the vconsole into utf-8 mode in case it has been set to
non-utf-8 mode for whatever reason. I.e, the following would leave
the console in utf-8 mode as expected:
# export LANG=en_US.ISO-8859-1
# /usr/lib/systemd/systemd-vconsole-setup
# export LANG=en_US.UTF-8
# /usr/lib/systemd/systemd-vconsole-setup

Command systemctl stop foo.service, will print error message, when
foo.service is unknown to systemd, i.e. there is no unit file loaded for
this service.

Restore the check that was removed in commit 74afee9c. Its removal
caused a regression on some s390x systems where for whatever reason the
device node /dev/tty0 exists and makes the preceding access() check
pass.
Some users found it difficult to understand what systemctl was telling
them.
Instead of "install information" talk about "[Install] section", which
is more likely to ring a bell. And suggest that it is intentional, so
that users do not attempt to "correct" the unit files.

Use the usual indentation, bracketing style, and no assignments in ifs.
Since check_listening_sockets provides just optional hints for the user,
don't pass its DBusErrors to the caller.
The "$action-multiple-sessions" polkit actions are defined as
"$action while other users are logged in". To me this implies that the
following sessions should not count:
- greeter sessions
- user sessions belonging to the same user as the one who's asking
Not sure how to treat class SESSION_LOCK_SCREEN. I never have these.
I just ignore every class that's not SESSION_USER.

Allow passing of basename only, instead of the absolute path; letting
systemd-tmpfiles perform a path lookup for the proper fragment path in
the config directories.
This allows distributions to call: systemd-tmpfiles <program.conf> on
upgrade of a package, with respecting the possibly overriden (or even
masked) tmpfile.
