Small source packages is a burden in *every* package tracking in Debian. Small binary packages is also a burden in *some* package tracking. Zero-size binary packages is also a burden in *some* package tracking, but I don't hear ftpmasters complain about task packages. This bug 976331 is *not* about repackaging embedded modules as separate *source* packages, but only about exposing embedded modules as *binary* packages - either virtual or real ones. - Jonas -- * Jonas Smedegaard - idealist & Internet-arkitekt * Tlf.: +45 40843136 Website: http://dr.jones.dk/ [x] quote me freely [ ] ask before reusing [ ] keep private
