Thanks for the support :-)

I don't think so...

I see ubuntu-desktop STILL says: "It is safe to remove this package..." in
the package description. I filed a bug about this about a year ago.
Either it should NOT say that or developers should stop telling us that we
_should_ keep the *-desktop packages installed.

Sure, he should - and most users do. We regularly see "I wanted to remove
X, but apt said it was going to remove ..." - after all, that's what
started this thread. However, once I agree to remove *-desktop, that's my

That's not really apropos. It's still the debian package system, and if
anything breaks without *-desktop it's _purely_ because the package was
built without proper dependencies.

Fine. And if that's the only issue (and I really think it is) then I can
safely ignore these dire warnings to reinstall the desktop package. I'll
find those fancy new feature by myself, thanks.

"suggests" is so soft it's squishy :-) "Recommends" is something like that,
in so far as aptitude installs those by default. Too bad you can't tell it
you don't want the recommends for a single package (I tried to install
eclipse with just the full dependencies, and aptitude tried to remove every
other "recommends" package).

I've suggested that before. Specifically, pre-dapper ubuntu-desktop
depended on postfix instead of "postfix | mail-transfer-agent". That's
moot now, but I'm sure there are plenty of other examples. Wherever
possible, ubuntu-desktop should suggest an optimal choice of dependency but
not force it when there are equivalent alternatives. The reason I
originally had to remove kubuntu-desktop was that I refused to run postfix
when all I needed was masqmail.

Indeed: a dependency of "kmail | mail-reader" would work right now - with
absolutely no modifications needed to mutt or kmail, since both
provide "mail-reader" (and "imap-client", for that matter).
