This seems to be some basic 'issue' with this image. See below

I ran yum update via an ssh session and saw the updated included:

selinux-policy.noarch 0:3.13.1-60.el7 selinux-policy-targeted.noarch 0:3.13.1-60.el7

Then on my serial console I see:

I just set up a new image on a sata HD, resized everything as I wanted with gparted, set selinux to switch to enforcing during first boot. I logged all the serial output, and see the following BEFORE it hit the selinux switch:

[ OK ] Reached target Switch Root. Starting Switch Root... [ 12.606603] systemd-journald[120]: Received SIGTERM from PID 1 (systemd).

So this is something in the image. In fact when the system rebooted after the selinux switch these messages occured again:

[ 402.784167] SELinux: Class netlink_iscsi_socket not defined in policy. [ 402.791081] SELinux: Class netlink_fib_lookup_socket not defined in policy.

[ 402.855145] SELinux: the above unknown classes and permissions will be allowed

Finally these messages occured related to the selinux switch:

Welcome to CentOS Linux 7 (Core)!

*** Warning -- SELinux targeted policy relabel is required. *** Relabeling could take a very long time, depending on file *** system size and speed of hard drives. Warning: Skipping the following R/O filesystems: /sys/fs/cgroup 4.0%[ 136.228323] systemd-readahead[353]: open(/etc/selinux/targeted/modules/active/policy.kern) failed: Too many levels of symbolic links

Do these warnings matter?
