Very preliminary RHEL7/CentOS7 SIOS base support

This is rebasing our SIOS tech atop RHEL7/CentOS7. Very early stage, pre-alpha, lots of debugger windows open … but …

[root@usn-ramboot ~]# cat /etc/redhat-release
CentOS Linux release 7.2.1511 (Core)
[root@usn-ramboot ~]# uname -r
[root@usn-ramboot ~]# df -h /
Filesystem      Size  Used Avail Use% Mounted on
tmpfs           8.0G  4.7G  3.4G  59% /

Dracut is giving me a few fits, but I’ve finished that side for the most part, and am now into the debugging the post-pivot environment.
Good times, as we can use the rebase for our RHEL7 appliances for Ceph and GlusterFS as well as others (RHEV/OpenShift).
