man/systemd-getty-generator fix/update * Containers don't use serial-getty@console.service, they use console-getty.service instead, and suppress scanning for kernel or virtualizer consoles. * Nowadays gettys are started on all configured kernel consoles. * except for the line printer console, because that's not a tty. (Seriously. Search CONFIG_LP_CONSOLE). 2017-08-07 20:30:56 +03:00			`Documentation=man:agetty(8) man:systemd-getty-generator(8)`

units: make sure container-getty@.service stops restarting when the pts device it is bound to is gone We only want to restart the getty as long as the pts device is still around. As soon as it is gone, the service should be removed to. http://lists.freedesktop.org/archives/systemd-devel/2014-December/026048.html 2014-12-09 04:12:11 +03:00			`ConditionPathExists=/dev/pts/%I`

units: add Conflicts=rescue.service to container-getty@.service The traditional runlevel 1 is "single user mode", and shuts down all but the main console. In systemd, rescue.target provides runlevel1.target. But it did not shut down logins on secondary consoles... if systemd was running in a container. I don't think we strictly need to change this. But when you look at both container-getty@.service and getty@.service, you see that both have IgnoreOnIsolate, but only the latter has Conflicts=rescue.service. This also makes rescue.target in a container consistent with emergency.target. In the latter case, the gettys were already stopped, because they have a Requires dependency on sysinit.target. 2017-08-07 21:24:32 +03:00			`# IgnoreOnIsolate is an issue: when someone isolates rescue.target,`

units: Tell login to preserve environment (#6023) Make agetty started by getty units pass '-p' option to "login", so it doesn't clear the environment and passes whatever was setup by systemd to shells. This is needed especially for programs which are specified as user shells, but won't read locale settings from anywhere but environment.
