How to prevent creation of SELinux contexts on files during kickstart installation?

Issue

• SELinux is disabled but security file contexts are not removed.
• "selinux --disabled" is used in kickstart file which disables the SELinux on the installed system but files still have SELinux context e.g.:

# ll -Z /root/
-rw-------. root root system_u:object_r:admin_home_t:s0 anaconda-ks.cfg
-rw-r--r--. root root system_u:object_r:admin_home_t:s0 install.log
-rw-r--r--. root root system_u:object_r:admin_home_t:s0 install.log.syslog

• SELinux contexts are not generated on the RHEL 6.2 system which was installed using same kickstart profile.
