I have not worked with 8.0, but have upgraded my 7.2 systems to the kernel that is in 8.0 (2.4.18). Even better than restoring backups, you can convert from ext2 to ext3 on the fly. The only proviso is hat you should (but don't have to) do it with the file system unmounted. You can do this with tomsrtbt, and probably with other single floppy disties. The main reason to upgrade while the file system is unmounted is that if the fs is mopunted, the journal goes into a file with a name (like any other file). You do NOT want to back up or restore that file! Better to build it while the FS is not mounted, and let the journal be created with no file name. None the less, make backups anyway!!! I suggest you make backups, do the upgrade to 8.0, then immediately upgrade your file systems to ext3, then put the box back in service and watch it closely, as you would with any OS upgrade. -- Charles Curley /"\ ASCII Ribbon Campaign Looking for fine software \ / Respect for open standards and/or writing?
