[Fedora-livecd-list] USB-Disk Bootable Fedora Core 5?

[George Nincehelser]

I know this is somewhat tangential to the list, but I was wondering if
anyone has had success making a bootable Fedora (preferably Core 5) on
an external USB hard drive?  (Not a flash drive, but an actual notebook
hard drive connected to a USB adapter)

I've gotten to the point where Fedora is installed on the HD, a new
mkinitrd is built to include the necessary USB modules, Grub configured,
etc.

However, when Fedora starts to boot, it eventually panics because it
can't find the volumes.  I've tried it without LVM, but that didn't
help.  It just panics on trying to mount the partitions instead.

I've gotten DSL running from a flash drive, but I'd really rather have a
Fedora install on a USB hard drive that I could run anywhere.  

Any insight would be appreciated!

Thanks
George
