CentOS - Jun 2010 - Kickstart issue: 'dialog' doesn't work in %post, CentOS 5.5

Hi, all.

I'm trying to customize a CentOS installation cd, but got trouble with
kickstart.

I want to use dialog[1] for command line based user interface, but it can't
display correctly in kickstart with CentOS 5.5. Same ks file works with CentOS
5.3 (both i386 and x86_64).

What's the different between CentOS 5.3/5.5? I can't find it in release
notes.
And how can i fix it?
Thanks very much. :)

My ks file:

# =========install
cdrom
key --skip
auth  --useshadow  --enablemd5

logging --level=debug
selinux --disabled

I cant comment on your issue here as such, but my the way to achieve 
something along the lines of what you are doing is to build and drop in 
a firstboot module that could then use the interface setup via firstboot 
for user interaction. Generally doing user interaction at the level you 
are doing, in a kickstart file, is considered bad practice.

What does "can't display correctly" mean?
Checked /etc/termcap for available terminals?
