I'm quite unaware of Debian best practices concerning packages. I guess we can't make "puredata" package to provide a vanilla version, though I feel like that's what it should have been. Puredata-core isn't meant to provide vanilla puredata, but only the pd library, so people will have to install core+gui+doc to get vanilla, which may be fine. I don't see any (meta-)package labeled "*-vanilla" in Debian repo, so I suppose it wouldn't be the right way of doing.
The idea behind also was to keep "vanilla" and "extended-like" well separated rather than providing a single package which is a mix of both. Until reinstalling my system I wasn't very attentive with the arbitrary part of recommended packages. So I've just set up my system accordingly not to install them by default. Hope this is fine ;) happy patching. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
