Oh, no worries, from Red Hat you can always expect the worse.
It is not true. RHEL is stable, reliable platform and now release 7 comes with nice features as well as finally they have recent packages, like Python 2.7.5, Apache httpd 2.4, Tomcat 7, dropped MySQL on favour of MariaDB, etc. In corporate environment usually RHEL is the only accepted LINUX platform. We are using 6.x without any issues, except, except lack of recent packages, see above. But with 7 it is gone.
CentOS now follows RHEL much faster then before as key developers are payed full time by REDHAT since January.
For me the problem now is only systemd, as setting up the system is changed and I have to relearn ho to manage the system which is wasting a time. But this is the life. Everything is changing.
