The exploit happens by mounting something to a very long path, crashing
systemd.

I'd like to remind everyone that the s6 init system, which is very
similar to runit, can handle a crash on its daemon supervisor, by
spawning another one. So even if s6 had the breathtaking attack surface
that systemd has, it still could not be exploited in this way.
