[syslinux] PXElinux Modification Question

Hi,
We are new to PXElinux and we are using it in our test lab
to do provisioning. When the systems come up there is a
PXElinux menu to boot local(default) or boot to the imaging
environment (linux). It works great, but we have to visit
each machine whenever we want to create or restore a disk
image.
Now we would like to be able to remotely force a system to
re-image itself. The stumbling block for us is how to get
PXElinux to default to the image environment rather than a
local boot. We don't want to have to change the
configuration file that is downloaded from the tftp server
every time we want to force a machine to re-image
(including messing with symlinks to different config
files.) Is there a standard way to do this?
One idea we had was to write some data into a free sector in
the first head of the first hard disk and modify PXElinux
to look there for a certain tag that specifies which image
should be booted. How difficult would it be to make this
modification to PXElinux? What problems can you see with
this plan? What resources are available for those of us
that are new to PXElinux development? Thanks for your time
and insight.
