I gave wrong information to someone who appeared on the channel today
(can't remember the nick).
Foreman on RHEL7 does work when SELinux is put to permissive mode.
Please report bugs.
Foreman on CentOS 7 does not work yet since SCL repositories for CentOS
7 haven't been released yet. Again, once released make sure SELinux is
permissive.
