To try and phrase things another way, all user intent is trying to track
is "do I want this package on my system even if it's not fulfilling any
dependencies." By far, the most common and significant indication of
this is whether the user typed "pkg install foo" or not. I would claim
this covers the vast majority of users, and haven't heard any claims to
the contrary. I don't believe that failure to perfectly induce a user's
desire means we should just punt on the question, especially since we've
had numerous complaints about this issue. That's why the proposal also
includes tools to allow the occasional user for whom we make the wrong
guess to rectify our mistake.
So now users need to worry about the system uninstalling pkgs that the
users might have wanted? The tradeoff seems to be be: don't save space
(and annoy users) or save space (and annoy users more).
Yes, users might be less annoyed this way, but, I doubt it. If it
doesn't work out you can always turn this off.
I guess we just have different opinions about what our user base looks
like, and neither of us has data to back it up, except for the
complaints we've received about current approaches. It's not just about
saving disk space, it's about providing the information needed to make
group packages work. Several times we've been told that the current
system of 'pkg install amp-dev'; 'pkg uninstall amp-dev' leaving large
numbers of applications on your system isn't helpful. This is needed to
fix that issue. It has the bonus of also making uninstall more generally
work as our users have told us they expect it to work.
Also, this will let us handle things like a package being obsoleted, so
it's removed from your system. Then it's resurrected. Now, do you want
that package back on your system or not? Well, that depends on whether
you manually removed the package yourself, or it was removed because it
was obsolete.
If you're right and we tick off a large number of users, we can always
put things back the way it was before.
