Use the source, Luke!
One of the main reasons to use a FOSS OS is that you can see the code! For me as a dev, it's been a lifechanging experience. Often it's faster to just look at the code than try to decipher Stack Overflow answers, and I always learn more that way!
Another perk of the *BSD's is that all of their source is in one repo. This can of course make SCM slow, but from a curious-developer perspective it's a dream come true.
OpenBSD uses cvs(1) to manage their source, but they publish a read-only git(1) mirror to GitHub, which I like to use for familiarity sake.
Traditionally, all the source lives in /usr/src , and OpenBSD expects you to put it there (for build purposes).
To get it:
# usermod -G wsrc,wobj <user>
# mkdir /var/git # chmod 775 /var/git # chown root:wsrc /var/git $ cd /var/git $ git clone --bare https://github.com/openbsd/src
$ git -C /var/git/src.git worktree add /usr/src
$ cd /usr/src/bin/ed $ make obj # for out of tree build, see make(1) OBJDIR $ make $ ./obj/ed
How cool is that?
