No doubt we'll still want to be able to run KDE 3 apps! But I'm not sure this
will necessarily mean relegating all of KDE 4 to some directory like
the /opt/kde4 I'm currently using. If we do that even when KDE 4.0 is
supposedly packaged as the default KDE, I'm worried that we're going to be
stuck with it forever, like SuSE was with /opt/kde3. (They're now moving back
to /usr with KDE 4, they do have the advantage of not having KDE 3 in there.)
Hasn't upstream eliminated most of the conflicts in /usr? I could envision
packaging both KDE 4 and compat KDE 3 stuff into /usr, and where there are
conflicts, just zapping the KDE 3 one. (For example, if it only affects
binaries like konqueror which we don't want or need in compat-kdebase3 anyway,
we can easily do that.) Of course, I still have to look at the alpha to see how
many conflicts there really are left. One definite problem will be the -devel
packages, the symlinks will unavoidably conflict. That's a problem most
compat-lib packages have, the most common solution is a Conflicts, but I don't
really like it. I hope we can think of an acceptable solution which is neither
a completely separate prefix nor a -devel conflict. Maybe putting the symlinks
into the already existing /usr/lib/kde3 or something similar (/usr/lib/kdelibs3
or whatever)? But that will probably need configure patching in some packages
which build against kdelibs3.
That was the KDE4DIR part. For what to do about KDE4HOME, that appears still to
be an open topic upstream. Speculations are that as long as we don't need to
run the KDE 3 and KDE 4 version of the _same_ apps, sharing the directory
should just work, but maybe some system services which are always there in both
versions can cause trouble. What I know for sure is that as long as there's
apps like Konqueror etc. in both kdebase 3 and kdebase 4, sharing KDEHOME won't
work. But as I said above, we probably don't want to install the KDE 3
Konqueror at all in F8. The only parts from kdebase 3 which would be
useful/needed in a compat-kdebase3 package are the loadable modules (KControl
config pages and such).
