Newer mkreiserfs overwrites the beginning of the partition to 
avoid that. Probably yours was created with a very old one.

Not hardly Jeff, where have you been?  Wetware refers to the brain of the

Part of the problem is that if a partition is formatted with mkfs.ext3,
it gets an ext3 magic number scribbled at a known offset into the partition.
If you then reformat it with mkfs.reiserfs, that scribbles a different
magic number elsewhere on the partition, but leaves the ext3 magic number
intact.  As a result, if you forget to update /etc/fstab, fsck.ext3 checks
for its magic number, finds it, concludes it's probably an ext3, and then
discovers that everything is totally scrogged.....

Yes, it's pilot error, but it's definitely hitting your feet with much larger
caliber rounds than you would have expected... :)

That's fairly old and unless the contents of your skull is even weirder
than I ever thought, the answer's "no".

Yep.   Needs to get fixed because when you upgrade from a reiserfs 
system and try to keep the reiserfs partitions and add a new hard drive 
(+1) to
an existing system, you run the risk of corrupting resiferfs partitions.

Since when does fsck run fsck.ext3 on filesystems that are not marked
as ext3 in /etc/fstab?

Sorry, but I doubt that Hans or anybody in RH knows how to patch wetware,
let alone one as messed up as yours.

Huh?  WTF are you trying to feed reiserfs to fsck.ext3 and just what do
you expect it to do?

If they all use the same on disk formats as their basic structure, fsck 
should not return gt > 1 due to misinterpreting reiser on-disk 
structures. It should say "oh not one of mine, skipping". Instead it 
returns an error claiming massive corruption, and halts the system. I 
just upgraded my wifes computer from Suse to RedHat FC4 and when it hits 
the reiser partitions, the whole system explodes due to fsck.ext3 
misrecognizing reiser partitions. I had to modify rc.sysinit and blank 
the partitions with fdisk to get it to install. After it installed, I 
recreated the partitions (after writing down what they were in the first 
place for block #'s etc.) and disabled rc.sysinit checks. This is 
busted. Hans needs to fix fsck.ext3 and submit a patch or redhat does.

I don't like #ifdef's in code. 

You could just have split up the quota-specific stuff into a function of 
their own: "ext3_show_quota_options()". The patch might have been larger, 
but it would actually clean up the code rather than make it uglier.

Warnings are not a reason for ugly code.
