Alternatively, if you have a set of machines you routinely keep in
sync via cloning a master image, then on the master you can modify
grub's menu.lst file to reference the old /dev/sdX style paths. Then
the clones should work fine.
ie. We have 5 travel PCs that have identical hardware. When a major
upgrade comes, we upgrade the master and test it out. Modify
menu.lst, then clone the rest of the PCs from the master.
James,
I assume you can modify menu.lst via yast, but I directly edit
/boot/grub/menu.lst
On my workstation with a default menu.lst file I have:
root=/dev/disk/by-id/scsi-SATA_ST3250310AS_9RY00PYW-part5
in the middle of my kernel boot line.
In my case that would simply need to be "root=/dev/sda5" instead. Not
the part5 and the sda5 are in sync. You need to do that as well.
