Hi,
Thanks a lot for so many helpful responses.
The fix is pretty straight: just mount /dev/pts again at the chrooted
%post environment where my original sshd fires up from.
One command 'Mount -t devpts -o rw,gid=5,mode=620 devpts /dev/pts' or
just a bare 'mount /dev/pts' command fix the problem since the devpts
entry is in fstab already.
I also hacked image stage2.img to include sshd daemon binary, libraries
and configuration files, and fire up the ssh daemon at the first line of
%pre script section. Then disable my original fired up sshd daemon at
%post section.
Now kickstart environment is not 'dump' at all -- I can kick into and
monitor the kickstart clients any time and stop run-away kickstart
processes with 'reboot' command immediately should my home directory
server upgrade turn into a disaster.

you may need to force ssh to allocate a pseudo-tty,
try "ssh -t -x <ksClient>". the -t option is described
in the ssh manpage.
