NFS in Mac OS X and Linux

I usually struggle to launch NFS shares, I guess I don't really understand them. Thankfully, two websites gave me everything in needed to get them going:

and

http://tldp.org/HOWTO/NFS-HOWTO/index.html

And for good measure, I found this page:

and this:

Since most of the links are Macosxhints I'll trust they'll be around for a long time!
