The pre-install is not inside a chroot environment, so whatever variables you set or export are only available for use outside of a chroot. And that’s the problem with the post install section, by default anyway.
Record the installation time and date, install files into the system, record installation date and time, find file overlays and installation scripts on a remote file system. You can do a lot with the post installation routine in a kickstart file.
