These are some thoughts which came from thinking about the problem of documentation for the Devuan Linux distribution. I wanted to take some time to think an opinion through here.
I don't think a Devuan install guide should exist, and any interested people would be more helpful upstream.
I would think "Devuan is Debian without systemd" means most documentation has already been done. It is a great position to be in, as it leaves only a few things to do:
1. Make it easy for Devuan users to find the equivalent Debian documentation, especially their basic install and user guides.
2. Write any documentation which doesn't exist in Debian, e.g non-systemd or on systemd-removal.
3. Rewrite "a better version" of any existing Debian documentation. This is a beautiful idea and a trap I adamantly oppose. Contribute upstream.
I think good software should make such basic documentation unnecessary. The current installer is fantastic in most places, making install documentation only necessary to:
1. Let non-programmers help cover a problem while the project waits for programmers to improve things and obsolete that documentation.
2. Document corner-cases, aid in troubleshooting, point people to user support or bug submission (even upstream to, or past Debian), and follow users around like biographers writing diaries of problems and solutions being brought up.
