Yeah, I think perspective is a large part of it. It's probably a lot
more common than one would think. I know for a fact that sendmail only
runs as a daemon with -bd (or -bD, though that way is a "foreground"
daemon) and Cyrus IMAP "master" process only runs in daemon mode with
-d. As a matter of fact, even udevd--the event managing daemon--only
runs in daemon mode with a --daemon switch. (And then there's vnstatd
and ...)
Generally, though, it's almost universally useful to be able to run a
daemon process in non-daemon mode (especially for debugging and initial
configuration), so nearly all *nix daemons are either configured to run
as non-daemon process by default and require a --daemon type switch or
are created to run as daemons by default and provide a --non-daemon switch.
