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: 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. 2013-01-05 01:36:48 +04:00			m4_ifdef(`HAVE_SYSV_COMPAT',

units/console-getty.service: comment reason for ConditionPathExists Currently we have 4 getty services. 1 has a BindsTo dependency on a device unit. 3 have ConditionPathExists, but the reason is different in every single one. * Add comment to console-getty@.service (see commit 1b41981d) * getty@.service is already commented * container-getty.service is not strictly correct, as I realized while trying to compose a comment. Reported as #6584. 2017-08-09 16:43:41 +03:00			`# OCI containers may be run without a console`

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. [zj: cherry-pick just the second patch from the series, see discussion on the pull request.] 2017-05-24 14:58:01 +03:00			`# The '-o' option value tells agetty to replace 'login' arguments with an`

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. 2012-04-24 16:28:00 +04:00			`Type=idle`

core: optionally send SIGHUP in addition to the configured kill signal This is useful to fake session ends for processes like shells. 2013-07-30 03:54:59 +04:00			`SendSIGHUP=yes`
