Description of problem:
NOTE: This is not exactly a bug related to mkbootdisk, but since this was the
only component I've found that related to /dev/fd?, I took it... =)

I've noticed that, after upgrading from RH 8.0 to RH 9.0, access to /dev/fd0 is
always read-only.

I'm currently logged in as root, but I am not able to mount /dev/fd0 in
read-write mode, even when 

> mount -t auto -o rw /dev/fd0 /mnt/floppy

This will _always_ result in a read-only floppy drive.

RH 8.0 worked well with my current system configuration.

Thanks for looking after it...

PS: /dev/fd0 node is ok, root is the owner, group is floppy, access rights to
the device are rwxr-xr-x

My System Configuration incl. a VIA KT 400 chipset (Gigabyte GA-7VAX board) and
otherwise standard hardware incl. the floppy drive (Mitsumi).

I would have posted an excerpt of /etc/sysconfig/hwconf here, but due to
limitations of the get method of this form (all form fields are sent via
url-encoding-scheme to the server) I have not been able to fulfill the request.

Perhaps you have a look at bugzilla, too.

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

How reproducible:

Steps to Reproduce:
1. install RH 9 on my system
2. insert disk
3. try to mkfs.msdos /dev/fd0
4. fail due to read-only device

Actual Results:  floppy disk is read-only, even when logged in as root.

Expected Results:  guess what =)
