A while back I used ltsp to network boot a bunch of servers.  I created a
file called

	/etc/init.d/customise_client

made it executable and linked it into /etc/rc2.d/ so the script ran on
boot.

The script did a bunch of things like:

	echo "w.x.y.z   hostname1" >> /etc/hosts 
	echo "w.x.y.z   hostname2" >> /etc/hosts 
	echo "w.x.y.z   hostname3" >> /etc/hosts 

It also ran something like:

	mac=`ip addr show eth0 | grep 'link/ether' | cut -f 6 -d " "`

to identify the machine by their mac address, then I had a case statement
which compared $mac to a bunch of known macs and made machine-specific
customisations.

This (particularly the machine-specific bit) is not very scalable and not
very pretty, but it suited my purpose.
