I'm using pxelinux (a derivative of syslinux as used on live cds) and the
config file for each system (based on ethernet MAC address) looks like

DEFAULT first_attempt

LABEL first_attempt
    kernel zotac/linux-2.6.30-gentoo-r4
    append ip=dhcp root=/dev/nfs nfsroot=

As you can see, the kernel and the root filesystem mount point are both
defined so you can set up whatever you want - very handy if like me you
have a mix of 64 bit and 32 bit frontends.

The dhcp stuff to get it to boot in the first place is handled by dnsmasq
which also uses MAC addesses to put a fixed IP address to each f/e. I'm
using the builtin tftp server in dnsmasq to serve up pxelinux and deliver
the kernel to each f/e.

Works well :-)
