  it's readable, yes.

  by running it bit by bit on the command line, and testing each
  command.  of course, you can clean up stuff like the above as well
  to make it more readable.  then again, how would you achieve the
  same as what the script does without doing just the same thing?

  not really.  there are reasons why one doesn't change the format of
  proc mounts.  it looks complex, and it is, but it's also very much
  tried and true.  one could argue about the lack of 'trap' or
  something similar tools in the scripts though.

  and a lot of scripts require a great deal of "magic" before they
  run.  why do you think the initscript for autofs looks the way it
  does?  because start-stop-daemon automount works?  :-)
