I agree with not including the mdadm.conf in the initrd. When the
initrd is built though, I'd check that the mdadm configuration stored
in the root disk's /init, which is tantamount to a config file, should
be checked against the host's mdadm.conf to ensure they match. If they
don't, I'd suggest yaird should fail. The user can then fix one or the
other.

(assuming you meant --run here) Primarily because it looks like a
--force option, which to me suggests the author was thinking, "This
may cause some damage, so make sure the user knows what he's doing."
I'd check with the mdadm author what he thinks of adding --run to
yaird.

No worries. Cheers,
