Dyson

I've set up Debian Patch Tracker: http://patches.osdyson.org/
It is incomplete and buggy, but no more than in Debian itself
Not so buggy already, see https://bugs.debian.org/745480

Patch tracker is useful to overview Dyson patches, usually
prefixed with "dyson-".

See for example http://patches.osdyson.org/package/fakeroot/
