I'll reinstall another vm and try it. I believe it may not however, as the startup script tries to allow it and fails for some reason.

From /etc/init.d/ypbind:

selinux_on() {
    [ -x /usr/sbin/selinuxenabled ] && /usr/sbin/selinuxenabled || return
    #echo $"Turning on allow_ypbind SELinux boolean"
    setsebool allow_ypbind=1
}

And:

start() {
  ...
  echo -n $"Starting NIS service: "
    selinux_on


And this doesn't work. But I'm also seeing other errors in init scripts, particularly autofs that I'm currently troubleshooting.

Thanks!
