While the release happened last week, I haven't had a chance to install it until today. Currently my laptop only supports 32 bit virtualization, so I had to wait until I had an extra box to try it out on.
CentOS 7 is now up to date with some of the underlying technologies. systemd has been present since 2011 being first incorporated into Fedora 15 and other distributions following suit after that. This technology is probably going to be around for some time just as the Sys V Init scripts were. Another change has been that of making firewalld the default over iptables for firewall control. Firewalld is a very recent addition to Fedora coming in Fedora 18. Initially I didn't like firewalld because it wouldn't save some rules I needed for forwarding packets. That seems to be resolved now in Fedora 20 by being able to manually make permanent iptables rules through firewall-cmd. Before that you would have to revert to iptables to get things done.
With a minimal install I had some issues finding the MAC addresses for my network cards because ifconfig did not come installed. That may be intentional with the minimal install, but it is a tool I consider essential and should be included. I ended up having to go through /var/log/messages to find the MAC addresses so I could get it connected. Thankfully getting ifconfig installed just involves bringing in the net-tools package.
Aside from that everything has been working fine. Right now I am using CentOS 7 to setup a web server for a forum and possibly MediaWiki. It is a welcome change to CentOS 6 which is showing its age pretty well with the lack of new but foundational technologies.
