Is this under repair on the install cd?

Yes, if the change was made in the repair disk, the kernel version will probably be different, and the paths are relative to the system's root. But the rename can be done while the system is running, so only the followin pass is missing: 0. vgrename ... > > I'd suggest that new Fedora releases create a random name for the VG and > > that their initrd/nash support getting the vg from the root= kernel > > command line. > > > > Regards, > > Luciano Rocha > > You don't think setting it to the machine name is any good?

Also, you might have two different installations with the same hostname (like a new install to a new set of hard disks). But I do use the hostname as the VG, so I think that's best, probably with current date appended (like: hostname080320). Regards, Luciano Rocha -- lfr 0/0
