I read on

"...daemons can simply write a line to a file descriptor of their choice,
then close that file descriptor, when they're ready to serve. This is a
generic mechanism that some daemons already implement."

I am curious, does anyone on this list know of examples of such daemons? I
am considering creating and submitting patches for some daemon programs
that I use that do *not* support this mechanism as yet, and am curious if
it is as simple as it looks like it should be.
