I never use the "--name" option when creating an md device but AFAIK it just allows you to refer to an md device with a name of your choice. I'm glad that it works but the "HOMEHOST <system>" is used at the creation of the md device so there must be another mechanism at work to allow for the assembly of "/" in spite of the change of hostname. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
