Changes in serial-getty@.service.m4 http://src.iws.cs.ovgu.de/source/rss/systemd/units/serial-getty@.service.m4 en Copyright 2005 Java 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. /systemd/units/serial-getty@.service.m4 - 4bf04322b8b7ecca4f3d65cfc642d0ac16356129 Michael Olbrich <m.olbrich@pengutronix.de> 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 /systemd/units/serial-getty@.service.m4 - fc6c7fe9becdd70ae6b671c396f2ad2db0b71cd7 Hendrik Brueckner <brueckner@redhat.com> 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 /systemd/units/serial-getty@.service.m4 - 7143555ce8f94b002d06b9b058d7d90c3a4901a9 Zbigniew Jędrzejewski-Szmek <zbyszek@in.waw.pl> 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. /systemd/units/serial-getty@.service.m4 - ccf22d4a104e6ed2666d6c5b4031981a84787790 Lennart Poettering <lennart@poettering.net> core: optionally send SIGHUP in addition to the configured kill signal This is useful to fake session ends for processes like shells. /systemd/units/serial-getty@.service.m4 - 82659fd7571bda0f3dce9755b89a23c411d53dda Lennart Poettering <lennart@poettering.net> 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). /systemd/units/serial-getty@.service.m4 - 7c1b8f043ed3d23663549dd6084c5a4de51b8e28 Karel Zak <kzak@redhat.com> 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. /systemd/units/serial-getty@.service.m4 - 83514a2fa0c9377e76dcc323ab7e7756b7f86cc4 Lennart Poettering <lennart@poettering.net> unit: link up getty configuration from man page and unit files /systemd/units/serial-getty@.service.m4 - 00addadd86aff6187f1b7abe23bf1c42241b42d9 Lennart Poettering <lennart@poettering.net> 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 /systemd/units/serial-getty@.service.m4 - 2161de72c517d34d1ceb9b4c1a300f0b54ce5a9c Michal Schmidt <mschmidt@redhat.com> 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. /systemd/units/serial-getty@.service.m4 - 9c2cd81e0ef9cf45adc6108eaea172d722f39321 Ramkumar Ramachandra <artagnon@gmail.com> 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. /systemd/units/serial-getty@.service.m4 - 7f2cddae09fd2579ae24434df577bb5e5a157d86 Lennart Poettering <lennart@poettering.net> man: document systemd-update-generator /systemd/units/serial-getty@.service.m4 - f5ccf26ded1fd7c3d5d9c7b6615236ae051b4a34 Lennart Poettering <lennart@poettering.net> 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. /systemd/units/serial-getty@.service.m4 - 49dbfa7b2b0bf3906704dac1eaeb4eba91056a19 Lennart Poettering <lennart@poettering.net> 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. /systemd/units/serial-getty@.service.m4 - f2b6878955b1f77ea1fa87b502b13d5dbefc57f6 Lennart Poettering <lennart@poettering.net> default to v102 everywhere, instead of vt100, to synchronize with agetty /systemd/units/serial-getty@.service.m4 - acda6a054fb131dbab9b7b16e4148e05a03ce66b Lennart Poettering <lennart@poettering.net> 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. /systemd/units/serial-getty@.service.m4 - 5430f7f2bc7330f3088b894166bf3524a067e3d8 Lennart Poettering <lennart@poettering.net> 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. /systemd/units/serial-getty@.service.m4 - 4771148bb92ace55eaa6759a53d04a0f2de9b0d2 Lennart Poettering <lennart@poettering.net> service: ignore SIGPIPE by default /systemd/units/serial-getty@.service.m4 - 353e12c2f4a9e96a47eb80b80d2ffb7bc1d44a1b Lennart Poettering <lennart@poettering.net> 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. /systemd/units/serial-getty@.service.m4 - 6fdae8a6a40d6a3b5f77516abaee23b3eab002f6 Dexter Morgan <dmorgan@mageia.org> 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. /systemd/units/serial-getty@.service.m4 - 6ea832a20700f5282c08c70f38422c6ab290a0b5 Lennart Poettering <lennart@poettering.net>
