I've thought about that, too, and will change that soon.. Also, a friend
of mine suggested building a meta-package that pulls in `essential'
modules. I'd rather not depend on any specific module being present, but
rather depend on at least one being there..

If anyone could tell me how to prevent dpkg to restart collectd $n$
times when installing $n$ packages I'll gladly do this :)

No, there's no such thing yet and none is planned so far. If you can
life with a limited interface to collectd one could write two modules
`exec_counter' and `exec_gauge' which exec a script/binary, read a
single value back and write it to the RRD file.

I don't see a way to intelligently handle definitions for RRD files from
the outside, so having one `value' DS of either type `COUNTER' or
`GAUGE' would simplify a lot.

Such a module has been written recently and will be included in the next
version. Assuming you mean logged in users.

If by usage you mean allocated and free blocks: This has been asked for
before, and I'll likely do that soon..
