Are there scripts that are really trying to parse the output of
mke2fs?  The output hasn't really been _that_ stable.  I'm sure we've
added stuff in the past, althoughg admittedly the this is the first
time that we would be removing stuff.

The block sizs is pretty much always 4k, and the file system label is
only there if the user specified one on the command line.  I can see
how the size and UUID might be useful, though.

How about if we just print the size and UUID?
