Comment 2 for bug 475064

Forgive my ignorance with the terminology, but as it's a "treeless shared repository" as I understood it from the docs let me just give you a bunch of sizes in the hopes that one of them is what you mean:

treeless shared repo '/var/lib/bzr/trunk': 20MB
treeless shared repo '/var/lib/bzr/.bzr/': 690MB
checkout of trunk '.bzr/': 666MB
checkout of trunk everything else: 179MB
