Why doesn't rdev work?

[Gerry Doris]

I've been playing with rdev on a Redhat 8.0 system.  If I create a
bootdisk using mkbootdisk it works just fine.

Running rdev correctly gives the result of

/dev/hda3  (ie. root is on /dev/hda3)

If I run

rdev /dev/fd0

on the newly created bootdisk.  I don't get /dev/hda3 like I was
expecting.  I get a hex value like /dev/0x3da5.  If I do a

rdev /dev/fd0 /dev/hda3

and then do a

rdev /dev/fd0

I get the expected answer back of /dev/hda3.  However, the bootdisk
won't work anymore.  What am I doing wrong.
