I haven't understood the details of your setup. But couldn't you run Knoppix (or one of the other Linux-on-a-CD's) and activate your LVM partitions with "vgchange -a y" (as root)? Won't "lvdisplay" then tell you the names of the corresponding devices? Then you could mount the partitions as you wish, and copy whatever you want from one to the other. > Another (related) question: is it possible, through grub, to have the 2 > systems (f8 and fc6) working?

Again, I'm not sure of your exact question, but it is certainly possible to have grub stanzas corresponding to different versions of Fedora. Personally, I would not rely on the Fedora installation to setup things as I desire. I would install F8, and then re-write grub.conf to contain one or more entries for FC-6. You shouldn't need to re-install grub, as far as I can see. -- Timothy Murphy e-mail (<80k only): tim /at/ birdsnest.maths.tcd.ie tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College, Dublin 2, Ireland -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
