      Add support for hashified/cloned filesystems. This is really only · 4bb9e149
      Leigh B. Stoller authored
      useful on widearea nodes where we can amortize the time it takes to
      copy/hash the necessary filesystems, which takes about 15 minutes.
      We would do this when a node first boots (or its image is updated I
      Note that the clone operation (when a vserver is actually created) is very fast
      though, taking about 30 seconds.
      Currently controlled by local variable $USEHASHIFIED for debugging.

      Some very basic infrastructure for generalized tools was added. · 639758e6
      Dan Gebhardt authored
      Some parts very "hacky", lots of XXX / TODOs.
      BARELY tested!!!! Don't use on the production system yet.
      Need to verify that things didn't break, especially with the automanager,
      the bgmon.pl "outage detection stuff", etc...
      See code's todos and also the file
      At this point:
       - mangerclient & automanagerclient did not change.
       - The manager, when a probe request is received, looks at the DB table
         "tool_spec" to retrieve the proper wrapperpath, formal parameter list, etc..
       - The manager assembles a message and sends it out to the appropriate
         path probers, which operate on the request as they have been
         (no major internal changes to the path probers).
       - The path probers call the toolwrapper to run the tests
       - The toolwrappers return a canonical result for that type of metric.
       - The path probers send the result and the actual parameters used by the
         tool to the data collector.
       - The data collector uses the toolname and actual parameters to get an
         idx number. This idx is stored in the "measured_by" field of this
         measurement's entry in the "pair_data" table.
