It also appears to be completely untrue. The way I read it, systemd will (optionally) dump core, (optionally) switch VTs, (optionally) spawn an emergency shell, and (unconditionally) freeze.Also systemd doesn't just abort on SIGSEGV, it serializes its state and then execs itself anew.Now that is neat.

That seems to be correct. There is logic in there for serializing state and re-execing itself which if I am reading correctly, is part of the startup process, so maybe the OP thought that was part of the crash recovery process. It seems that there is some infrastructure such that the described recovery _could_ be attempted, in the same fashion that it drops to /bin/sh on SIGSEGV,SIGILL,SIGFPE,SIGBUS,SIGQUIT,SIGABRT

Uh, yes, sorry, I had misunderstood what someone told me in systemd's IRC channel.
Anyway, if you configure systemd to spawn a shell, you can exec systemd from there, so not everything is lost.
