I haven't looked at Debian's scripts here, but whatever Debian uses as
init scripts to control mdadm startup is decided by the Debian mdadm
maintainer. We do carry a set of system files for mdadm in the
mdadm/systemd directory, so if something is missing, it may be that the
Debian maintainer forgot to include it.
