I was planning to but actually I spent some time struggling to build a
decent rpm package. Finally the kind fedora folks have more or less done
this for me [¹] :-)

As I try to avoid entropy on production servers by not circumventing the
package manager, the next step for me is to build a nice package with the
source from the HEAD of Florian's branch. Then push it on the machines...

In any case, I'll keep you informed of any trouble encountered.

I just spent some time testing with different "instance" parameters, which
work just fine.

I was also working on a reasonable varnish config for
contrib/collection3/etc/collection.conf, but maybe I should wait until
Florian settles down with the way instances and types are named...

This seems quite sensible to me.

I would find the stuff about running threads would be nice too:

   n_wrk                N worker threads
   n_wrk_create         N worker threads created
   n_wrk_failed         N worker threads not created
   n_wrk_max            N worker threads limited
   n_wrk_queue          N queued work requests
   n_wrk_overflow       N overflowed work requests
   n_wrk_drop           N dropped work requests

I'll be glad to upload a couple of graphs as soon as I have some "real"
ones. I've added a note concerning this linking issue Florian diagnosed.
