Comment 10 for bug 986892

I have tested installing mysql-server-5.1 in 11.10, and then doing a dist-upgrade to get to precise.

Ok so the problem is that mysql-server-5.1's postrm runs *after* mysql-server-5.5's postinst creates the file. This is because we only have a 'Breaks+Replaces' relationship between the two, so dpkg correctly:

* deconfigures 5.1
* installs 5.5
* configures 5.5
* removes 5.1

This really does need to be fixed in dh_apparmor. The postrm snippet should simply not rm the local/ file if the primary file is still in existence, since it is basically guaranteed to still depend on the local/ file.
