Also worth noting: if you remove a conffile and then think "Oops, I
didn't mean to do that, let me reinstall the package to get it back",
you will be surprised. The conffile will not be replaced. Your action
of deleting the conffile while retaining the package is explicitly
noted by the package manager, and respected as a conscious choice.
If you want to replace a deleted conffile, you may either *purge* the
package and then reinstall it, or use the --force-confmiss flag to dpkg.

tasksel will also perform an autoremove for you without asking you.
It was after this happened to me that I investigated how to disable
apt's autoremove feature.
