[syslinux] advice wrt pxelinux & tftpd & dhcp

[Jim Cromie]

Ive got a mucho-kludgo (but working) setup where;

pxe-client boots an os-du-jour in runlevel 2,
rc.2 runs a test-script that ends in a reboot,

meanwhile, on tftp-server host,
a script watches the syslog, notes the arrival of an RRQ message for a 
kernel,
and runs a program to rewrite the pxelinux.cfg/default file so that
it causes a different kernel to boot the next time.

This setup lets me cycle thru a set of kernels/configs and test them all.

The question is obvious;
is there a better, more robust way to do this, using a combo of
pxelinux, tftpd, and dhcp-server (on redhat box, but Ill get new 
executables if needed)
