4bf04322b8 units/serial-getty@.service: use the default RestartSec
For pluggable ttys such as USB serial devices, the getty is restarted
and exits in a loop until the remove event reaches systemd. Under
certain circumstances the restart loop can overload the system in a
way that prevents the remove event from reaching systemd for a long
time (e.g. at least several minutes on a small embedded system).

Use the default RestartSec to prevent the restart loop from
overloading the system. Serial gettys are interactive units, so
waiting an extra 100ms really doesn't make a difference anyways
compared to the time it takes the user to log in.

fc6c7fe9be getty: Start getty on 3270 terminals available on Linux on System z
Add the first 3270 terminal device that is associated with the Linux preferred
console to the list of virtualization consoles.  This is required to
automatically start a getty if the conmode=3270 kernel parameter is specified
for Linux on z/VM instances.  Note that a queued upstream patch also enable
the 3270 terminal device if it is associated with the Linux preferred console.
How

To successfully start agetty on a 3270 terminal, a change in the agetty
parameter order is required.  Previously, agetty would started like this:

    /sbin/agetty --keep-baud 3270/tty1 115200,38400,9600 TERM

The agetty program interprets the "3270/tty1" as baud rate and fails to start
with the "bad speed: 3270/tty1" error message.  Fixing this in agetty is more
complex rather than reordering the command line parameters like this:

    /sbin/agetty --keep-baud 115200,38400,9600 3270/tty1 TERM

According to agetty sources and "agetty --help", agetty accepts the "tty",
"baudrate tty", and "tty baudrate" specifications.

P.S. The "tty: Set correct tty name in 'active' sysfs attribute" introduces
     a change to display the terminal device which is associated with the
     Linux preferred console.  This change helps to let systemd handle this
     particular case only.  Without the changes of this commit, no additional
     3270 terminal device can be managed by systemd.

7143555ce8 units/serial-getty@.service: add [Install] section
This makes it easier to manually enable and disable
specific gettys, and also mirrors getty@.service.

ccf22d4a10 units: when spawning a getty configure TERM explicitly
This way we can make use of our logic to automatically determine an
appropriate TERM for a specific tty.

7c1b8f043e units: cleanup agetty command line
* baud rate is optional and unnecessary for virtual terminals
 * term type is optional (default is 'linux' for virtual terminals
   and 'vt102' for serial lines)
 * long options are more user-friendly

... all this is supported since util-linux v2.20 (Aug 2011).

2161de72c5 units: agetty overrides TERM
Environment=TERM=... has no effect on agetty who sets it by itself. To
really set TERM to a specified value, it has to be given on the command
line.

7f2cddae09 unit: rename BindTo= to BindsTo=
all other dependencies are in 3rd person. Change BindTo= accordingly to
BindsTo=.

Of course, the dependency is widely used, hence we parse the old name
too for compatibility.

49dbfa7b2b units: introduce new Documentation= field and make use of it everywhere
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.

f2b6878955 service: introduce Type=idle and use it for gettys
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.

5430f7f2bc relicense to LGPLv2.1 (with exceptions)
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.

4771148bb9 units: exclude gettys from isolate requests
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.

6fdae8a6a4 Add Mageia support
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.

1de4d79bf5 build-sys: add Mandriva distribution support
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

60b4f27794 serial: use TERM=vt100 instead of TERM=vt100-nav
TERM=vt100-nav was necessary for compat with some ppc hvc devices, a
long time ago. Unfortunately vt100-nav terminfo is not installed by
default on most distros, hence change the default to v100 which is
available universally and still should be a relatively safe and
conservative default.

Should it turn out that vt100 is not really the best choice we can
revert this change again and then ask distros to move vt100-nav into
their default install.

The property StopRetroactively= needs to be per-dependency, not

and its .device and fsck .service units. If the .device unit is
unplugged the mount should go away, but if the fsck process terminates
the .mount should stay.
