Sure. I'm a freebsd user now myself (after 10+ years of linux).
What I'm saying is:
1. If one documents how unix software works on different unixes, linux
must be included. It's too important. Fringe systems such as openserver
can be skipped, linux not.
2. Since there have been multiple major changes in the 2.4 series, it's
reasonable to assume that there will be more (in 2.4 and/or 2.6), and
"document how program x works on linux vm" is then a bad policy.
3. 1 and 2 combine to make "document it" a bad policy in general.
Documentation is good. But it's not a cure for all ills.
