Description of problem:
When doing an install with kickstart and a %post-script, the following
error appears (copied by hand):

Traceback (most recent call last):
  File "/usr/bin/anaconda", line 1090, in ?
  File "/usr/lib/anaconda/kickstart.py", line 1318, in setInstallData
    self.readKickstart(id, self.file)
  File "/usr/lib/anaconda/kickstart.py", line 698, in readKickstart
    where = self.readKickstart(id, args[1], where = where)
  File "/usr/lib/anaconda/kickstart.py", line 758, in readKickstart
    script = script + n
UnboundLocalError: local variable 'script' referenced before assignment
install exited abnormally

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Build installable CD with buildinstall
2. Add kickstart script to it (with %post section)
3. Boot the CD

Additional info:

It is not clear to me where the variable "script" is supposed to be
assigned, so I can't fix the bug myself.

Can you save the complete dump and attach it?  I can't reproduce this
here (I do lots of kickstarts with a %post that always gets run).  Any
odd kernel messages on tty4?

Kickstart file that causes the problem

Here is the kickstart file that causes the problem. The traceback I posted
earlier is all I get as far as I can tell.

Comment 3 Benny Amorsen 2004-04-08 09:24:29 UTC
Heh, off to change the default root password now... Duh.

Comment 4 Jeremy Katz 2004-05-06 21:50:20 UTC
Is this reproducible with newer trees?

Comment 5 Benny Amorsen 2004-05-07 11:53:54 UTC
The problem persists with anaconda-9.92-8. I haven't tried anything
later. I have an ugly workaround patch.

I am seeing this bug also.  My commonality with this kickstart script
is that I'm using %includes (much more frequently in my case however)
in %post, as well as all other sections.  I will be happy to attach my
ks.cfg if you desire.

Comment 8 Jeremy Katz 2004-10-04 20:31:13 UTC
Finally reproduced.  Fixed in CVS.

Comment 9 Michael Rice 2006-02-01 17:54:31 UTC
I had this problem in 3ES U4 with a kickstart config with both %include and
%post scripts.  Remove either and it didn't generate the error noted above.

The fix is VERY similar to Benny's, but I pulled the code from a 4ES U2 anaconda
where the readKickstart method is very similar.  

Patch attached.

To use this loopback mount your stage2.img file somewhere, copy all the files to
a working directory.  Patch $workingdir/usr/lib/anaconda/kickstart.py with the
attached patch.  mkcramfs $workingdir /tmp/stage2-patched.img

copy the /tmp/stage2-patched.img to your kickstart base directory (e.g.
