How- release cycle. Red Hat Enterprise Linux release schedules do not follow that of Fedora around 6 months per release but are more conservative 2 years or more. Red Hat then moved towards splitting its product the Fedora 12 release and released more or less together line into Red Hat Enterprise Linux which was designed to with Fedora By the time RHEL 6 was released, many be stable and with long-term support for enterprise users features from Fedora 13 and 14 had already been back- and Fedora as the community distribution and project ported into it.
The Fedora Project lists the following lin- sponsored by Red Hat. Also, the rebuilds do not get access to Red some cross-pollination between the two up until shortly Hat services like Red Hat Network. This practice however, still tribution.
CentOS developers vate rapidly with new technologies. Red Hat had no objections to the change since they do not make Enterprise Linux is a commercial enterprise any changes to the kernel beyond what is provided by Red operating system and has its own set of test Hat.
