You shouldn't need to, the /tmp/ should be the same at that point for the
%include (It was when I was doing this).
You should be able to add a simple 'read JUNK' into your %pre to pause it
there so you can check VT2 and see if the file was created properly, or just
cat it at that point to another of the VT's.

I'm using something similar to this, to define network arguments:

--gateway=`/usr/bin/echo ${GWADDR}` \

...to no avail. I see the literal contents (IPADDR=`/usr/bin/echo )
inside my system config scripts, instead of the extracted value being
written to these files. I've even gone so far as to get rid of my echo
statement in an attempt to get it to work, as well as just placing
${VARNAME}, to get more familiar with how Anaconda extracts these values
trying to find my mistake.
I'm sure what I'm doing is not overly complicated - but for now, I'm
stuck. If anyone has any feedback, I'd be very eager to hear back from
you.
Kickstart doesn't have any provisions for reading environment variables
or capturing the output of programs like you're trying to do. However,
you can do this stuff in a %pre script, as that just gets fed to the
shell (or whatever you set the interpreter to). So you could write a
pre script that generates the dynamic chunks and writes it to a file,
then %include that file up in the command section.
That should work.

Hello again, Chris -
I'm using %pre to write to a file called /tmp/netsettings. I'm then
trying to %include it from within my commands section.
Every time, I'm given an error saying that /tmp/netsettings cannot be
found. I cannot verify this, or it's location, because Anaconda bombs out
and locks up vt2.
I think I'm lost in chroot land. Do I need to mount a disk in %pre in
order to write my temp file? What would you suggest?
Thanks!
-dant
