Never, ever, try to do that (again). Mdadm (or vgscan, or whatever)
should NOT assemble ALL arrays found, but only those which it has
been told to assemble. This is it again: you bring another disk into
a system (disk which comes from another machine), and mdadm finds
FOREIGN arrays and brings them up as /dev/md0, where YOUR root
filesystem should be. That's what 'homehost' option is for, for
example.
If initrd should be reconfigured after some changes (be it raid
arrays, LVM volumes, hostname, whatever), -- I for one am fine
with that. Hopefully no one will argue that if you forgot to
install an MBR into your replacement drive, it was entirely your
own fault that your system become unbootable, after all ;)

Exactly. So make it /all/all local/, if you must. It's the same as
far as I'm concerned.

Feel free to be fine with it, as long as you also let me be free to
not be fine with it and try to cut a better deal :-)
