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.

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. https://git.kernel.org/cgit/linux/kernel/git/gregkh/tty.git/commit/?id=723abd87f6e536f1353c8f64f621520bc29523a3

units/serial-getty@.service: add [Install] section This makes it easier to manually enable and disable specific gettys, and also mirrors getty@.service. http://lists.freedesktop.org/archives/systemd-devel/2014-February/017329.html

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.

core: optionally send SIGHUP in addition to the configured kill signal This is useful to fake session ends for processes like shells.

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).

units: drop distro specific stuff from units Since rc-local is now enabled via the SysV compatibility we should only refer to it based on that too.

unit: link up getty configuration from man page and unit files

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. https://bugzilla.redhat.com/show_bug.cgi?id=870622

units: teach m4 scripts in units/ about Debian's rc.local This makes the behaviour wrt. to rc[-.]local consistent between various distributions supporting it.

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.

man: document systemd-update-generator

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.

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.

default to v102 everywhere, instead of vt100, to synchronize with agetty

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.

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.

service: ignore SIGPIPE by default

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.

exec: hangup/reset/deallocate VTs in gettys 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.

exec: drop process group kill mode since it has little use and confuses the user

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

build-sys: update ALTLinux support Please apply patch for update ALTLinux support.

units: synchronize gettys to plymouth even if plymouth is killed by gdm

plymouth: ensure we start not a single getty before plymouth is gone because we never know which ttys plymouth still controls

serial-getty: invoking /sbin/securetty is no longer necessary since pam_securetty can now look for console= in /proc/cmdline

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.

units: set TERM for gettys again, since they acquire a TTY on their own

units: delay getty until logins are allowed

exec: automatically determine right TERM= setting based on tty name

units: make use of agetty mandatory

units: deal properly with the fact that agetty is called getty on Debian

unit: replace StopRetroactively= by BindTo= dependencies The property StopRetroactively= needs to be per-dependency, not per-unit, in order to properly express dependencies between .mount units 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.

units: enable utmp for serial gettys too

service: rename settings for Restart= from 'restart-always' to 'always' and similar

serial: use seperate getty template for serial ttys
