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.
