Very interesting.  Unfotunately, my results don't match yours.

First, I had tried 'file' and found that it didn't work.  I tried it 
again and found that it still didn't work.

    root@notsomarlin:~# losetup /dev/loop/0 /tmp/foo
    root@notsomarlin:~# mke2fs /dev/loop/0
    ...
    root@notsomarlin:~# file /tmp/foo
    /tmp/foo: Linux rev 1.0 ext2 filesystem data
    root@notsomarlin:~# mkreiserfs /dev/loop/0
    ...
    ReiserFS is successfully created on /dev/loop/0.
    root@notsomarlin:~# file /tmp/foo
    /tmp/foo: data

Do you get other results?  If not, it would seem that Debian's version 
of 'file' is broken, yet I checked the source code and there are magic 
numbers for reiserfs included.

Also, I check e2fsprogs and it is at version 1.35 in Debian unstable, 
but no tool called 'blkid' is included.

So I'm still searching for reliable methods to do this.
