The FreeBSD package system doesn't really have the concept of a special command to remove files that are part of a package but which are user editable and preserved when the main body of the package is removed. In general, preservation of local configuration is handled in one of three ways: i) It isn't preserved at all. Deleting the port/package will delete the configuration files you spent hours tuning to be just right... ii) The port installs sample configuration files which you have to copy and edit as part of the installation. Thus the configuration file doesn't count as part of the package and will be left behind when the package is deleted. iii) Very similarly to (ii) a sample configuration file is installed but the actual configuration file is automatically created as a copy of the sample if the actual file doesn't exist. At deinstall time, the sample and actual configuration files are compared, and the actual configuration file will be left untouched if they differ (implying that the actual configuration file has been modified). Remember that in FreeBSD as upgrading a port/package involves a deinstall followed by an install of the new version, so configuration file handling is something that most porters pay quite a lot of attention to. Packages that use method (i) tend to be quite rare in the tree nowadays. This does mean that if you delete a bunch of installed packages you tend to be left with a scattering of miscellaneous files which you would have to deal with manually if you wanted to get rid of them. Generally those files will be found in ${PREFIX}/etc/ (usually /usr/local/etc, but quite often /usr/X11R6/etc) or subdirectories thereof. Note that this only applies to 3rd party software installed via ports/packages. The base system has a completely different mechanism for handling updates.
