It was far simpler than that and did not involve copying data. You can
change the hostname using one of the mdadm management commands AFAIR (I

You can specify device names for md devices on the kernel command line,
but an option to ignore the hostname would be handy and just keep the
current naming system, at your own risk, would be handy.
