Understanding http://skarnet.org/software/s6-rc/why.html depends on
understanding the exact meanings of "supervision suite" and "service
manager", two phrases sounding confusingly similar to me (and I doubt
I'm the only one). Also confusing is sometimes use of "supervision
tree", which I assume is a synonym for "supervision suite." And then in
your email reply (above), you refer to "process supervisor", which I
assume is yet another synonym for "supervision suite."
The supervision tree is the tree of Unix processes that represents all
your supervised daemons. It goes like this:
init
\_ s6-svscan
\_ s6-supervise foobar
| \_ foobard
\_ s6-supervise bazqux
\_ bazquxd
... it's a tree.
(Sometimes, s6-svscan *is* init.)
What I call a "supervision suite" is the whole suite of programs, i.e.
the s6 package as a whole. What I call a "process supervisor" is the
subset of programs directly involved in process supervision, i.e.
s6-supervise and s6-svscan.
Do you think a glossary page would help? A page that defines the various
terms that we use daily, and that people who are less familiar with
supervision and service mangement could refer to?
