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.

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.

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.

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.

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.

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

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.

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.
