I agree red-hat manuals are excellent (when i used redhat) also in
debian/ubuntu you find very good docs (be it wiki, howto's, or online docs)

"In reality, documentation is a very important part of what Red Hat sells,
even if you can get it for free. First and foremost, it empowers more users
to take advantage of Red Hat software, and with more users, there are more
contributors and more potential customers. Second, good manuals establish a
bond between Red Hat the company and the end user. By educating users, Red
Hat convinces them that it cares about them and can make something as
complex as Linux make sense to them. And when those users want to pay for
service and support, to whom would they naturally turn?"
