You mean, the backing files ("path /dev/zvol/whatever", for example), right?
I thought about it. Problem is, while it makes it somewhat easier in very simple
situations, it's not very useful in real life - ctld (or CTL) has no information what
the permissions should be, should the file be fully or thin provisioned (in other
words, whether it supposed to be filled with zeroes, truncated to a correct length,
or perhaps it's a ZVOL with reservation set), etc. And you don't want it to create
files when you make a typo in path name.
