grub 0.95 + FC3 + 2.6.10-1.770_FC3smp on an Opteron.
I'm trying to make a bootable sysdisk clone.
My real sysdisk is /dev/sda, the clone is /dev/sdb
I've got a device-map file which maps hd0 to /dev/sdb
and hd1 to /dev/sda. When I issue the 'setup'command
to grub, it does some work then segfaults, and the
clone sysdisk is unbootable. Any ideas?
Cheers,
Terry.
