Description Karel Zak 2005-10-11 04:17:33 EDT
+++ This bug was initially created as a clone of Bug #168989 +++

Description of problem:
If you specify an offset value larger than 2GB (2^32) for losetup or mount -o
loop you will not get the expected result (i.e. it will wrap).

-- Additional comment from kzak@redhat.com on 2005-09-21 17:15 EST --
Ah.. good catch. The offset option in losetup in FC3, RHEL3 and RHEL4 is based
on "int" datetype. The problem is fixed in FC4. 

In FC3 it will be fixed in next util-linux update.

This issue is on Red Hat Engineering's list of planned work items 
for the upcoming Red Hat Enterprise Linux 3.8 release.  Engineering
