First, the changes I made to the installer to support the Cubieboard2 worked. However, I still needed to add "console=ttyS0,115200" to the append line in __boot/extlinux/extlinux.conf. I thought I saw that this was 'fixed' and was there? Or was it that I no longer need this on the append line? During 1st boot I caught the following. Is it important? find_file: stat /proc/device-tree/chosen/bootpath, No such file or directory After 1st boot, I logged in as root. I stopped sshd, as I am on the IEEE 802 network and I don't trust it so much to leave even SSH running in a fresh install. I right away did 'yum update' And got a number of messages then it stopped: Updating : selinux-policy-targeted-3.13.1-92.fc21.noarch 67/169 [ 1612.410834] SELinux: Permission audit_read in class capability2 not defined in policy.

What is it with the urgent call to test a systemd bug fix? I did not really see the system hang after 15min (or maybe that is why the cleanup stopped?). I might be able to run another test tomorrow night.
