Ideas for completing WIP "add unit to switch back to initrd at shutdown" etc

[Ray Strode]

Hi,

It sounds like you've put a lot of thought into this.  Are you
interested in working on it?

Those were never meant to go to master. They were just a quick draft
branch that snuck onto master when I was pushing some unrelated fixes.
It was incomplete, untested, and probably doesn't work. This problem,
in general, is on my back-burner radar and I haven't had time to work
on it (RHEL has been taking up a lot my time recently)

So I'm actually unhappy with plymouth-drm-escrow because I don't think
it's actually necessary. systemd has a feature we can use instead:
`sd_pid_notify_with_fds` and `FDSTORE=1` so I think i'd rather if the
branch was reworked to leverage that, so we don't have to deal with
the lifecycle management of a child process etc.

The rest of what you said makes sense to me, and it seems like you've
thought of more corner cases than I did.  If you want to pick it up
where I left, let me know.  Sounds good to me.
