According to Vincent's mail, the actual problem is just systemd.
Changing the kernel just for making one specific userland program
(which happens to be written by somebody, who even doesn't know the
semantics of rm -R) happy, sounds pretty strange for me.

I'm not opposed to the general idea of having a dummy tty driver,
but please for some actually sane usecases, not just working around
broken userland :p
