With a few exceptions, I see most admins treat CentOS as a single rolling release and rely on the ABI commitment assuming things just work between point releases. On the other hand I see the opposite with RHEL where admins constrain installations to the point release.
What is the case with users on this list who support both?
Only time we use CR is on *some* servers during the upgrade to a new subrelease. Otherwise, nope.
When I was a sysadmin for a living, I used CR in my test/staging area to see if everything worked. After I worked out all the kinks, I then either used CR on my production servers and/or waited until the actual point release, based on how close the release was going to be after I finished evaluating in testing/staging.
In general, for CentOS Linux 6 and before .. CR takes 3 or 4 days and final release is usually 14 to 21 days.
For CentOS Linux 7 (because of more rebases to newer versions that are much less conservative than EL6 and before) CR usually takes 10-14 days and final point release 35 to 42 days.
So, the delta in both cases (from CR done to final point release) is 2 to 4 weeks after CR rpms are released.
