And having a Root_Dir variable in the default file would help too.

The config directory is determined by DHCP option 210 if one is present,

otherwise by the filename used to fetch pxelinux.0 itself.

Now, there is a catch here -- this is the filename as provided by the 
DHCP stack.  At this point, chainloading a new pxelinux.0 doesn't change

this; this may be possible to change although it is dependent on the PXE

stack.
