Basically just a few filesystem-specific paramters need to be added
to the switch table in common.rc:

 - mkfs paramters if the default mkfs.$FSTYPE invocation doesn't do the
   right thing, or ask for confirmatio when doing things like
   overwriting existing filesystems or working on whole disks (not sure
   if anyone but extN came up with that last weird thing)
 - mount paramters for a successfull single node mount with acls and
   xattrs enabled
 - fsck options to actually force a real check even if the filesystem
   is mounted clean (and is nessecary to not make it wait for user
   input)
 - optionally an entry to create a filesystem with a given size for
   ENOSPC tests.
