Package: apache2
Version: 2.2.17-3

From /usr/share/doc/apache2/README.multiple-instances:

| MPMs
| ====
|
| You can use different MPMs for different instances by setting
| APACHE_HTTPD to one of /usr/lib/apache2/mpm-*/apache2. Note that
| some modules like mod_php only work with the non-threaded MPMs
| (prefork, itk).

Along with the magic in /etc/init.d/apache2, /usr/sbin/apache2ctl and
the other scripts that recognize -$favour suffixes, this works like a
charm to run multiple instances in parallel.

Unfortunately, the Debian packaging prevents the co-installation of
multiple Provides/Conflicts: apache2-mpm fields. The only file that is
actually conflicting is /usr/sbin/apache2 - this could easily be taken
care of by making it an "alternative". It is already a symlink, it
would just be managed by update-alternatives instead of being shipped
in some package. (Maybe with a raised priority for the "default" MPM.)

I would be willing to write a patch for this if the maintainers don't
think there would be an objection to enabling multiple instances with
different MPMs.

Thanks for considering,
Christoph

Oh. We were completely missing the fact that the actual MPM is shipped
in apache2.2-bin and not in the apache2-mpm-* package. I should have
noticed that before, it was probably too surprising to me as a design
choice to ship only the symlink in the package.

This solves our problem, thanks for the hint and sorry for wasting
your time. I'm closing the bug.
