This seems to be a recurring user question.
Do you consider this addition useful?
I think rcctl(8) is the best place to document it because that's
the highest level user interface and "How do i run multiple copies
of a daemon?" is a very high-level user question, while rc.d(8)
and rc.conf(8) document lower, more technical levels.
I'd love to make the example more specific and document an actual
use case that frequently occurs in practice, but even though many
have said that such cases do occur, i can't think of any. For
example, for httpd(8), it looks like all use cases can be solved
by running one copy and using "server ... { ... }" well in
httpd.conf(5). So, if anybody can describe a specific use case to
make the example better, that's quite welcome.
I certainly don't want an example in the style of
# ln -s httpd httpd2
That's a terrible name. The next admin coming along will have no
clue what this second httpd is needed for.
Yours,
Ingo
