I know. But there is /dev/hda6/boot/grub/menu.lst that says root is hda6, and /dev/hda7/boot/grub/menu.lst which says it is hda7. Which is used? And does anyone know where apt decides where root is? It doesn't get the info from the menu.lst used to boot the system, nor from fstab - it seems to be stored in a config file that was used during the install, I've discovered as a result of my copy of hda6 to hda7.

Well, yes, that's what I did, since I had two bootable Ubuntu installations. :-) The thing I'm trying to fix is apt messing up menu.lst because it has noted that it was originally installed to hda6 (I theorise). And I'm wondering which menu.lst grub will use to boot from. Or does it look for /boot/grub/menu.lst across all partitions and do a union of all the bootable kernels it finds? luke -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
