I've checked the Live CD that I have and it doesn't have "/etc/mdadm.conf". The install that I made with the Live CD does have one though, which I find confusing because I thought (incorrectly it seems) that a Live CD install is made from the same image as the Live CD itself. It doesn't have "HOMEHOST<system>" but it is set to automount some arrays. I don't know through what mechanism arrays are renamed when they are assembled on a "foreign" box and *stay*renamed* when are re-assembled on the "home" box. I know that it's happened to me and others with more than one distribution and that the resolution is to boot from a rescue disk, run "hostname <host>", and assemble the array(s) with "--update=homehost".
