Syslinux - Nov 2010 - Random numbers in pxe config

Is there a way to produce random number for pxemenu?

   For example i need to balance load between 10 web-servers, so I need
   something like:
     APPEND netboot=http://boot-serv-$RANDOM10/system.img

   Another example is when 1000 boxes starts up at the same time (after
   e.g. Datacenter power failure) it'll be useful to have random values in
   timeout:
     TIMEOUT $RANDOM120

At this time, all config files are static.  That said, you could use
gpxe/gpxelinux.0 instead of core/pxelinux.0 and retreive your config
from an HTTP server that runs a server-side script to make this
randomized data.
