Nothing new...
My thought as well. I've used CVS for the same in the '90s, and it worked quite well - I hated the guts of SCCS and always tried to stick with RCS instead which didn't have the anal locking that SCCS sported.
I've never gotten around unleashing git on /etc/ though (although my "dotfiles" are there and it's very nice). There's enough stuff in there to make it maybe worth a try, although these days Chef/Puppet/Ansible/Salt/... are probably more appropriate.
Biting the hand that feeds IT
