Yeah, a wiki would be useful but unless we can get a group of us (at
least three people) interested in working on it (and get access details
sorted out) I'm reluctant to set the request for a kernel.org autofs
wiki in motion.

I must admit I'm not keen on having to maintain a wiki site, as I've
said before, purely because in my experience, it's actually quite a bit
of work to make and keep it useful.
