Problem is:

There are cool superblock magics for reiserfs. And for ext[23]. And
even for good old Minix. Cool.

However, there are also ugly file systems, such as fat for
example. Fat has been defined as "something that can be read by a fat
driver", which can be pretty much anything. You can't really detect
whether it is fat. Even Microsoft only guess whether some FS is fat or
not.

And don't say detect it via a partition table. There are a lot of
cases where you get absolutely no or wrong information out of it, and
there are also lots of cases where you plainly have none.
