Summary:                    losetup not working
Description: 
Hello,

It seems I'm unable to have a working losetup inside my busybox.
I'm trying to mount an iso image through NFS from a busybox env launched
from PXE.

I've read http://bugs.uclibc.org/view.php?id=498  and thought I found
the issue, so I desactivated devfs, but it doesn't help.

I tried 1.01, 1.1-pre, svn version, and they all fail in a different
way:

1.01: NFS mount doesn't work :-( so I can't have access to my iso image.
But as 1.10 has some interesting features for my project, I'd prefer to
use it.

With 1.1.0-pre1 or SVN: 

# losetup /dev/loop7 /tmp/isodir/rhel3-1.iso
losetup /dev/loop7: Invalid argument

Kernel is a RHEL 3 one (2.4.21 based), loop module is loaded and attached
is my .config:

Any hint would be welcome.

A colleague using my tool has reported that it works without issue on a
RHEL4 so it could be a problem uniquely on a 2.4 based kernel.

Huh.  Since svn 12582 went in Nov 29 and this bug was created Dec 20 and
you say you tried current svn, I'm assuming that didn't fix it for you. 
Despite this, I just re-checked losetup and it's working for me.  More
info?

Similarly, svn 11289 fixing NFS mount went in at the end of October, and
it worked for _somebody_...
