Been there, done that, noone cares enough.  Would take a policy change I
suppose, to enforce it.

>From my poor memory, the "generally agreed best idea" is to setup two
packages, vaguely like this:

Package name: task-abc
Conflicts: task-abc-remove
Depends: abc, bcd, cde, def

Package name: task-abc-remove
Conflicts: task-abc, abc, bcd, cde, def

If someone cared enough to do that for all task packages, that would make
removal of tasks "simple".  I don't think this will happen soon, because I
get the feeling the the "powerusers" who would have to create the -remove
packages don't use task packages to begin with.  Making a sweeping
generalization, most people who have root don't install task packages, if
they want KDE they apt-get install koffice konquerer and let apt figure out
all the dependancies.  In other words they already know the names of the
tools they need, so they don't need a task package crutch.  Then I could
complain that the newbies that could benefit by the installation of
everything to do task-abc will probably not be able to figure out what's
installed by the task package or what in general is installed on their

Ideally task-abc-remove would even remove itself once it's done.  That
would be hard, but it might be possible via a nasty combination of at,
cron, and who knows what else.

Other theories included enforcing the addition of a file in /usr/sbin, for

# filename /usr/sbin/task-abc-remove
# This shell script cleans out task-abc
dpkg --remove abc
# you get the idea
dpkg --remove def
dpkg --remove task-abc
rm /usr/sbin/task-abc-remove

This is also somewhat tricky, as youd have to create
/usr/sbin/task-abc-remove as part of the postinst of task-abc.
