[$] Debian still having trouble with merged /usr

The addition of the "/usr merge" feature has been something of longstanding messin the Debian world. It seems like a relatively innocuous change, whichis in keeping with the practice of most other distributions at this point; it effectivelyeliminates the top-level /bin, /sbin, and /lib*directories in order to move their contents to the corresponding locationsunder /usr. But ever since we first covered the feature introduction forDebian-more than six years ago-it has a been a recurring series ofheadaches within that community. Recent events have seemingly simplyprolonged the pain, though perhaps the end is in sight.
