I've been running Debian for years so I'm aware of it. ;) There are
good examples of similar situations in Debian, logcheck being one of the
better ones. This situation however is solved in Debian (to the best of
my knowledge) by the package being configurable from an init-style
directory of files where every package that wants to make adjustments to
the logcheck configuration creates a new file based on it's package
name. This removes the possibility of conflicts. This doesn't map well
to our situation where adding support to SB requires adding messages
both to SB classes as well as classes of the package being linked to SB
(in this case Jacaranda). This would be analogous to Debian packages
having to jointly modify a logcheck configuration file AND adjust their
own configurations based on whether or not logcheck was installed.

Yes, this is not a pressing issue and I'll be looking forward to how
things compress. I was primarily trying to figure out what to do with
SBJacaranda in the immediate term but then mixed it with speculation
about long term plans. If this issue has already been considered or is
on the plate to be considered, that's great.
