[lug] Migrating an existing installation to a new hard drive (fwd)

[John Karns]

Oops, forgot something regarding running lilo on the copied fs.  Before
running lilo, you should create a copy of the lilo.conf in /mnt/etc, e.g.,
/mnt/etc/lilo.conf.new.  Then change the "disk =" reference from the
original device, to reflect the device of the 2nd hd.  Then execute lilo:

- after the copy is complete, "cd /mnt; chroot . sbin/lilo -C
/etc/lilo.conf.new"

But it may be easier just to boot from a rescue floppy or CD and run lilo
with the new disk replacing the old.

What I usually do in such a case is (as root):

- mount the destination disk (e.g. at /mnt)

- mount all the partitions on the destination disk (/mnt/usr, etc.)

- issue the command (as one long command - it's wrapped here)

find / \( -path '/proc' -prune -o -path '/mnt' -prune \) -o -print | cpio
-p -dmuv /mnt

(using 'V' instead of 'v' as a cpio parm will speed things up slightly, as
it won't print the filenames but rather a '.' for each

- after the copy is complete, "cd /mnt; chroot . sbin/lilo"
