Is that really necessary? Can't we just leave it as-is, so the number of
changes is minimized for now? On systems that don't have external
metadata arrays (i.e. most of them) mdmon won't be running anyway.

Well no, because it needs to run after all filesystems have been
unmounted and root is read-only. Unless ofcourse you change mdadm-raid
to run after root has been remounted read-only, but I do not know what
consequences that change would have.

Well I still think this is more a bugfix than a new feature, since right
now the functionality is there, it's just broken.
