Then even existing intiramfs image could (probably) be mdmon-agnostic.
Actually:
chroot /run/initramfs mdmon --takeover --all
worked just fine (after preparing new root - so after all mount --binds,
and before pivot_root(8)).
So in context of systemd instead of sysv scripts - a fork / chroot /
exec mdmon / wait - instead of killing it would do the thing, followed
by pivot_to_new_root().
Actually anything that could benefit from "immortality" in one or the
other way (perhaps udevd, so e.g. lvm doesn't need --noudevsync ? - when
taken over inside dracut's shutdown or anything similar after going back
to initramfs) that can be pre-chrooted into /run/initramfs and exec'ed,
should work just fine. For the record, udevd worked properly with pivot
survival.
