How do I translate between UUID --> (hd,0) --> dev/sd* notation? Grub will happily use regular device notation instead of UUID. However, when I say "regular" I mean /dev/hda1, not hd0,0. Strange, that. You can also find the UUID with "sudo tune2fs -l /dev/hda1," changing "hda1" to whatever partition you want the UUID for. I have been told that the UUID is better because it points at a specific place on the platter, where /dev/hda1 may move around depending on what the user does. Fine. And how often have I moved partitions around and messed up my booting because of it? Never. I haven't even heard of anyone who has ever done so. I wish they'd just dump the UUIDs for Grub.* *I did end up with a messed up pointer in menu.lst, but not because of anything I did. An update to a new kernel failed to realize that my file system was on a software RAID, so it put the new files on one disk only and told menu.lst to look for them on the other disk. I've done my share of dumbass moves, but that one wasn't my doing. > 2) Using Intrepid Install CD to manually install new partitions then > don't actually partition, then install grub. Problem?

Besides, some of us have only enough knowledge to answer the boring newbie questions. If there were no boring newbie questions we'd have nothing to do. Or we'd try to help someone with serious problems and end up seriously messing things up. _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
