in your initrd, having set the hostname correctly first.  It might do
exactly what you want.

I'll give it a try some time tomorrow, since I won't turn on that
noisy box today any more; my daughter is already asleep :-)

But then, I could use my own desktop to test it :-)

FWIW, here's the patch for Fedora rawhide's mkinitrd that worked for
me.  I figured even without --homehost it worked fine, even without
HOMEHOST set in mdadm.conf.

I hope copying mdadm.conf to initrd won't ever hurt, can you think of
any case in which it would?
