I can confirm I did not see such a notice... But it would be a great idea to add one. Generally if I see such a notice, I will simply abort the install, unless it is clear what policy is needed to be added. Just if I go to install software on Windows and it tells me to turn off my virus scanner, I abort the install.
But in this case I doubt SELinux is the culprit:
[root@media1 automated install]# ausearch -m AVC,USER_AVC -ts recent
<no matches>
No actions are being denied. I see why. It looks like I did actually disable it a few yours ago and forgot to reenable it... So I correct my self. SELinux is not in enforcement mode.
[root@media1 automated install]# ./basic-install.sh
