Ok, so if I read that correctly the effect would be that the meta package gets
installed but is left unconfigured because the binary package conflicts. While,
I think, with the conflicts in the meta packages too, the meta package would
reject being installed.
So thinking further, maybe this would allow de-installing the binary package,
then installing the meta package, but leaving any previous meta package alone?
Which probably could be an issue.
Which we already should have on Maverick then. Just that maybe not many people
really do this.
