Strange problems with dialog in %post

[Daniel Segall]

Hey all,

I'm trying to finish up some custom kickstarts, and I'm down to this last
problem. I run a post-install script (using dialog) with a series of
questions for adding a machine to our environment (NIS, IP, etc). I
figured out how to get them working interactively with the chvt command,
and everything works as it should.

My problem is that I'm getting strange (ascii?) characters in all of my
dialog boxes where the lines (borders) should be. I have tried several
variations to my dialog commands, but none has worked. If I go to vt2 and
manually run the script, it shows up fine, so I believe the problem is
something environmental to vt3. Like I said before, everything actually
works, I can input the info it asks for, and it progresses through the
different dialogs just fine. It just looks messed up. Below are the
important sections of my ks.cfg & the post install script it calls.
