The "chain loading" thing had me confused for a while. If you get PXE to
load "pure" gPXE / iPXE then yes, you do need some careful DHCP
configuration to avoid it loading the same thing again (and again...).
gPXELINUX avoids that complexity, since it is basically PXELINUX but
with gPXE / iPXE extensions and you don't need to do anything special to
DHCP whereas you can load the kernel and initrd over FTP or HTTP etc.
There are some specific instructions for the chain-loading config for
dnsmasq here: http://www.etherboot.org/wiki/dnsmasq
