But it will have it in next release... What changes have you seen that affect using CentOS as a server? Sure, the GUI has changed over the years to be more like Windows, but most of my servers don't even have a GUI installed. I have servers running CentOS 4, 5, 6, and 7. The only differences I can think of between 4 and 7 that affect server administration are selinux and systemd. Selinux can be easily disabled if you don't want to deal with it. I don't like systemd at the moment, but that's at least partially due to only having worked with it for a couple of weeks so far. The more I use it, the more I get used to it. So far, it seems easy enough to use once you figure out the new commands and file locations. -- Bowie
