Comment 1 for bug 992276

I'm in disagreement on this interpretation and given the fact that no other packages (that I can find) pre-install anything into /srv.

I understand it as /srv is a location for site specific data that is intended to be independent of the packaging system.

There is a lintian error specifically for it:

http://lintian.debian.org/tags/dir-or-file-in-srv.html

So if we really do move to /srv we'll need a debconf question for it, create the directories, permissions and such from postinstall if the administrator agrees to it. Also would need to support modifying where the default database stores it.
