One thing noticed missing on testing...
docker package is missing from SL7. Just downloaded and installed Centos 7, and it has it (via yum).
Checking into a little more, it's in the extras repo (default enabled with Centos). Could not find an extras repo on SL7 (no yum config to add it, or an entry to update in /etc/yum.repos.d, but was a rather quick scan, could of missed something).
PS: I did have a strange issue where network seemed to go out on me at logout and come back when I first installed a few days ago, but has been stable after disabling networkmanager, and I noticed those packages were updated so it might be already fixed.
Overall, everything else I tested so far seems to be good besides missing packages...
