how is the documentation for RHEL/CentOS?
So I'm curious about the documentation on the "stable" war-horse OSs. I am impressed for example on the community support of Ubuntu, Slackware, and impressed by the formal documentation of Arch and Gentoo.
1. However, how does the documentation of CentOS/RHEL compare to some of the other distros? and
2. How about compared to similar OSs, like Debian
note: I am primarily curious about reference/Wiki/Docs etc, not just forum community.
