Also I'd appreciate guidance where best to file it.

During boot I want to mount an iso9660 file as a loop device. The iso
file is on a ext3 partition labelled HUGE_01 which is mounted at
/mnt/huge.

FILE = /mnt/huge/get/iso/Fedora-12-i386-DVD/Fedora-12-i386-DVD.iso
MOUNTPOINT = /mnt/Fedora-12-i386-DVD.

The mount succeeds. However during boot I get this unnecessary failure message:

Mounting local filesystems: [ OK ]
[snip]
Mounting other filesystems:  mount: according to mtab
/mnt/huge/get/iso/Fedora-12-i386-DVD/Fedora-12-i386-DVD.iso is already
mounted on /mnt/Fedora-12-i386-DVD as loop  [ FAILED ]

From a user perspective, this error message seems equivalent to:
"Because we tried unnecessarily to mount this device a second time
after it had already mounted successfully, we now report to you that
the second attempt failed."

So a failure is reported where no failure occurred. Worse, a failure
is reported for the reason that it already succeeded. This seems
illogical and unnecessary. Unless I'm doing somethin' stoopid.
Relevant details are below.

Thanks,
David

There's a secret way to do this, called "man fstab." Those numbers at the end of the line are not random, they control the mounting order. So you are trying to mount the DVD file before you mount the filesystem providing the ISO image file. Change the "0 0" to something reasonable, I think "1 3" will work, or "2 1" if it doesn't.
