hi ya thedore
multiple ways to clone a disk for other pcs..
- from floppies
- across the net
- local disk on the other ide/scsi cable
- ...
- dont use dd/dump ... no point in copying ( dd'ing ) a 95% empty
partition to the target
i'd clone multiple machines this way ( from a master server )...
( with all the patches and updates already applied
( with a non-interactive script clone.sh + fdisk.sh )
- add the target disk as /dev/hdb
- fdisk can be automated by preloading the values too
separate partitions for ( /, /tmp, /var, /usr, /home, swap)
/tmp, /proc, doesnt need to be copied
- local disk copying is not susceptiable to network hiccups
<clone.sh>
-- i prefer multiple partitions for this tar mess
hda# fdisk.sh /dev/hdb
hda# mount /dev/hdb[1.n] /mnt[1..n]
hda# (tar cf - /bin /dev /etc /lib /root /sbin ) | \
(cd /mnt/hdb1 ; tar xvfp -)
# hdb2 is /tmp
hda# (tar cf - /usr ) | (cd /mnt/hdb3 ; tar xvfp -)
hda# (tar cf - /var ) | (cd /mnt/hdb5 ; tar xvfp -)
# hdb6 is swap
# i prefer /opt/home instead of /home
hda# (tar cf - /opt ) | (cd /mnt/hdb7 ; tar xvfp -)
# make the missing directories
hda# mkdir /mnt/hda1/{mnt,proc}
hda# chroot /mnt/hdb1 ; lilo -C etc/lilo.hdb.conf
# fix your ip# for the new machine if any
hda# mail -s "clone #1,001 done" thedore < /dev/null
</clone.sh>
take hdb to a different pc.. and it should boot as /dev/hda ...
-- if you dont want to plug in /dev/hdb into the "master"
- use a boot/root floppy that can mount your master to the target
or vice versa.. and still run the (non-interactive) clone.sh
-- the scripts that was used before... for hundreds of disks..
( some things in the old scripts is sorta broken but some manual stuff
( is good to see that the disk is live before running the cloner

- fun stuff was a way to automating fdisk..
