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.

machinectl: add new command to spawn a getty inside a container

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

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.

units: add Documentation= field to console-getty.service

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.

container: spawn a getty instead of a sulogin in a container
