Currently, if no format is specified for a new disk volume, we pass the
invalid value "none" as the FS type to 'parted mkpart'.
There doesn't seem to be a way to have parted not format the drive, so
just default to using 'ext2' in this case: this shouldn't cause any harm,
since we are creating a new partition in the first place.
