  Just out of interest, has anyone found a useful script to use with the
  map clause. When I fiddled with it, I found that the script has to
  output to stdout the name of the config to use. My script ended up
  being something like:

  #!/bin/sh

  echo "eth0-home"
  #echo "eth0-work"

  And I would just edit it to change it. It seemed to me that it would
  be difficult to write a script that dynamically worked out what
  network you were in. Either that or it would have to interupt the boot
  process to prompt the user for a location.

  What would a useful (for automation) script look like?
