What are the default settings in debconf's configuration?

Question

I had to run dpkg-reconfigure -a for certain reasons, and consequently given options for configure debconf. But I don't really know how those change things, and want to use the default settings.

Answer 1

Formulating Nimmermehr's answer into 2 commands that do the trick:

linenum=$(cat /var/cache/debconf/config.dat | grep -n 'Name: debconf/priority' | cut -d: -f1)
sed -n "$linenum,$(($linenum + 4))p" /var/cache/debconf/config.dat

Answer 2

One way is to open the debconf template database /var/cache/debconf/templates.dat with your favourite text editor and search for the entries of the package debconf (debconf/frontend and debconf/priority). The entries have the property Default which specifies the default value.
