Entirely my fault, but still: removing the line

. /usr/share/debconf/confmodule

from a DEB source package's post-installation file (ie: debian/postinst) results in the package not being configured at install-time any more. I would have never expected that sourcing the debconf module is in fact the way that automatic package configuration is invoked (I always assumed that dpkg invokes the config script just as it invokes the postinst script).

In not-entirely-unrelated news: the 0.9.6 release of TokenTube is only days away and features a plugin architecture (including a plugin for running Lua scripts).
