I have serverhostname.mydomain.net:1 there, perhaps due to creating arrays
not on install time, but long after the OS has been already installed and set
up properly with all the networking, domains and hostnames.

In any case, you can change that name to your liking, and then replace
"UUID=..." with "name=..." in mdadm.conf, if that helps anything with your
intended configuration.
