Exactly -- and that's what I was after.

`grep console= /proc/cmdline` and playing sed games with a script
during %pre gives me the "console=<args>" stuff which was appended
to the kernel during PXE.

I.e. my script could return something like "ttyS0,9600n8" for a
serial console install, and "" for a VGA install.

That script in %pre builds a very simple %include file which contains
a "bootloader --append=<args>" string, which I then use in the general
section of ks.cfg .

One less bit of hardcoded data in all my ks.cfg files -- thanks to all!

cheers,
sr.
