Well. I'd like to upgrade my parent's box from 8.10 (intrepid) to 10.04 LTS (lucid).
Doing this from the package manager should work, but I want to get a backup of the system if things go haywire or something stops working on this laptop. (After all, I did have serious gfx-driver problems after my last upgrade.)
The ubuntu thread on this is rather vague and googling gets me lost in the details, which I currently do net much care for.
This box has 2 other partitions (apart from swap), one with Windows (came pre-installed, I'll not remove it) and one a FAT32 partition to swap data btw. Ubuntu and Windows (IO prefer to mount the NTFS boot part. r/o)
My specific question(s) now are:
- Will backing up 8.10 with tar and restoring this tar file on the upgraded 10.04 work in principle?
- Will I have to do anything about grub when restoring?
Which toplevel directories do I need to exclude from tar? (
bin dev initrd.img lost+found opt sbin tmp vmlinuz boot etc initrd.img.old media proc srv usr vmlinuz.old cdrom home lib mnt root sys var
What about the symlinks? (initrd.img, vmlinuz)
- When restoring with tar, will it delete any files 10.04 has added to the harddisk?
Note that I'd also be fine using dd to make a full disc image -- but I assume I would then need to boot from the live CD to restore?
