John Marino updated daemon(8) on DragonFly. For some reason, I didn’t know it was a standalone program. I knew about the idea of daemons as helpers based inside the computer, which is why so many server programs end with a ‘d’ – sshd, ftpd, and so on. Inexplicably, I never actually saw the program itself.
A running description of activity related to DragonFly BSD.
IIRC daemon(8) is used to make arbitrary processes run detached from the controlling terminal, and is not used for most standard daemons (like sshd(8)), which IIRC would call daemon(3) directly.
