Does Holyoke have linux clusters for student use? If so I'd be interested to hear how the transition has gone...

Have you looked at System Installation Suite?
http://wiki.sisuite.org/
apt-cache search systemimager
Basic idea:
* Make a golden master
* Make an install CD that gets clones minimally booted and networked
* Image the machine from the master
Takes care of hostname tweaks etc.
The instructions provide enought detail to make it look complicated, but
when you get down to it, it's really easy.
dd is also an option, be careful about bad sectors etc. Also presumes
identical disks.
Otherwise, do something like:
* create master. make note of it's ip/network hostname
* boot clone w/ knoppix cd
* get shell, and 'sudo -s' to be root
* ssh [EMAIL PROTECTED] 'sfdisk -d /dev/hda' | sfdisk /dev/hda
* maybe do 'fdisk /dev/hda' and a write (type 'w') to make sure you call ioctl so
kernel re-reads partition table
* mke2fs as req'd
* mkswap as req'd
* mount /hda/<root partition>
* mount /hda/<other partitions>
so you end up with something like
/mnt/newroot
/mnt/newroot/home
/mnt/newroot/var
etc.
Then rsync data over:
* rsync -avz --hard-links [EMAIL PROTECTED]:/ /mnt/newroot
Then edit /mnt/newroot/etc/ files that make specific mention of hostname
or ip address as req'd.
This is from memory, so I'm sure I skipped or mistyped some crucial step
that will drive you mad.
Oh, like the mbr...
Maybe something like this to copy the boot record:
* ssh [EMAIL PROTECTED] 'dd if=/dev/hda bs=512k count=1' | dd of=/dev/hda
THis looks really cool. But at the moment there's no network, no imageserver, no nothing -- I'm starting form scratch in the basement of a housing project.... So I think I will try this method once I've gotten things up and running.
