I completely agree with you. (sidenote: what should a package do when
it attempts to register a file that is already registered? How should
update-alternatives be handled? Should update-alternatives support
this scheme and automatically register the file to the correct

Also, I think it should be dpkgs responsibility to delete all files
and directories belonging to a package (when purging the package).
(not sure about update-alternatives).  It should keep track of any
files/directories which can't be deleted too.

For example, if I try to purge xyz, but for some reason it can't
delete /etc/xyz/ (for instance maybe the system administrator
accidently moved an important file, like /etc/passwd into

Current situation: Either:

1. dpkg would print a warning (which is easy to miss), completely forget
about the directory, and mark the package as purged.
2. maintainer script would "rm -rf /etc/xyz".

Ideal solution:

dpkg should remember these files so that a latter attempt to purge the
package will succeed, and so you don't have old directories sitting
around doing nothing.
