You can recognise the filename by the fact that it starts with a "/",
since most of our stuff doesn't work with relative pathnames for block
devices and we don't want it to try to make it work now.
So the specification string should always be either
someprefix:[stuff]
in which case you strip off someprefix: (perhaps making a note of its
implications) or
/somepath
in which case you've got to the end and know what to do.
Ian.
