Whole device (i.e. a disk device that is not partitioned) cannot be registered as a diskdump-dedicated device.

Version-Release number of selected component (if applicable):
kernel-2.6.9-24

How reproducible:

This is not a regression but just a bug. So I change the summary.
A whole device cannot be configured for diksdump on the earliest
kernel-2.6.9-x. However, there is a workaround for this problem.
A partitioned disk device can be used as well as a whole device.
diskdump's users only partition a disk device with fdisk and
the like even if they need to use a whole device as a dump device.

Regards,
Akira

I plan to include this fix in the next release because
this problem has an impact upon other little, and also
requires a lot of testing. However, I need to update
the README file that is included in diskdumputils so that
users can know that a whole device cannot be configured
for diskdump on RHEL4.

Regards,
Akira

This issue is on Red Hat Engineering's list of planned work items 
for the upcoming Red Hat Enterprise Linux 4.4 release.  Engineering 
resources have been assigned and barring unforeseen circumstances, Red 
Hat intends to include this item in the 4.4 release.
