I got a good boot out of kernels that normally fail.  I booted
systemd's emergency shell and enabled a few services, in the same
order they normally start.  journald started cleanly, but after that,
every single command produced a "traps:" output and an "audit:" line.

I disabled systemd-journald (chmod -x, because `systemctl disable`
didn't really disable it), and now it boots, no "traps:" in the log.
If I run it, everything fails again (zsh has traps for simply pressing
enter on an empty cmd).
