OK, now reading again Guillem's reply I clearly see the problem. Mostly, I didn't see any other use for the fingerprint reader than authenticating someone. However, from [1] I can see that there're already fingerprint projects other than authentication, e.g. a SANE backend. > If, by an error in design, libfoo1 and libfoo0 conflict with each > other (e.g. by having both a binary /usr/bin/foo-tool), then it will > be impossible to have both bar and baz installed in the system. > That is the pain Guillem was referring to. Full ACK, I agree that we need separate packages. Thank to both for the explanation! Thx, bye, Gismo / Luca Footnotes: [1] http://wiki.debian.org/FingerForce
