Subject: Debugging kickstart general advice sought

Hi
I am debugging a problem with my kickstart but am founding
it immensely
cumbersome to rebuild a machine everytime just to test the
last part of
the install a stubborn pre-post script that does not want to
work. I'
will probably ask a question about it here later on.

Can anyone suggest a more productive way of debugging
kickstart files
that takes up less time than actually building a machine
each time?

Regards

I use sleep between commands so I can see whats going on,
and do my 
testing in VMWare. Still cumbersome though.

	What I do is to use the following trick:

	%pre
	(
	commands
	)|tee -a /tmp/pre.log

	%post --nochroot
	(
	commands
	cp /tmp/pre.log /mnt/sysimage/root/pre.log
	) |tee -a /mnt/sysimage/root/post.log


	And of course, lot's of "echo", and
"read" if you want to do some
pause ;)

	Regards
	Pablo

If your just debugging, you might want to just install the
core
systems and additionally install the packages that are used
for the post script.  In this way you wont have to install
1000 packages but just a couple of hundred.

Yikes,

I imagined that there could(should?) be a way to do a
"state" change that would allow you to return to a
previous state/position in the kickstart and try something
again. 

Does anybody use the debug mode or now how to use it? I am
not sure how to start it at will.

Aggreed, I do that already and my install is very small,
relatively
anyway. It takes about 1min30sec, but that is still a long
time to wait.

Does the tee trick catch all stdout and stderr messages?

This is why I use vmware for testing, you can let the
install get up  
to the point where you want to test, create a snapshot, let
it  
continue, and then roll back to that snapshot at any point.
