I wanted to answer
https://www.reddit.com/r/linux/comments/9q3b9v/custom_linux_distro_based_...
with an easy "well, I don't know about Debian, but here's how you do it for
Fedora"... but it turns out we don't have a great page I can just link to.
https://fedoraproject.org/wiki/Infrastructure/CustomSpins is both out of
date and short on specifics, and
https://fedoraproject.org/wiki/Remix is too
high level.
Our mission is meant to accommodate and encourage this. We should explain
better how to actually do it. Any volunteers?
