      Thanks for the response!

      I'm glad to know that there is a simple answer. The main cause of my
      concern was from reading the "Odd Behaviour" section at:
      which seems to me to quite clearly suggest that the issue applies to
      2.3R63 as_well_as Unslung6.

      The same page also states that the odd behavior occurs when the root
      device is on USB1 as you suggest.

      I think that I'll just use a 2.3R63 box for my NAS server and get a
      second slug to play with Unslung.

      Thanks again,
