      Replace license symbols with {{{ }}}-enclosed license blocks. · 6df609a9
      Eric Eide authored
      This commit is intended to makes the license status of Emulab and
      ProtoGENI source files more clear.  It replaces license symbols like
      "EMULAB-COPYRIGHT" and "GENIPUBLIC-COPYRIGHT" with {{{ }}}-delimited
      blocks that contain actual license statements.
      
      This change was driven by the fact that today, most people acquire and
      track Emulab and ProtoGENI sources via git.
      
      Before the Emulab source code was kept in git, the Flux Research Group
      at the University of Utah would roll distributions by making tar
      files.  As part of that process, the Flux Group would replace the
      license symbols in the source files with actual license statements.
      
      When the Flux Group moved to git, people outside of the group started
      to see the source files with the "unexpanded" symbols.  This meant
      that people acquired source files without actual license statements in
      them.  All the relevant files had Utah *copyright* statements in them,
      but without the expanded *license* statements, the licensing status of
      the source files was unclear.
      
      This commit is intended to clear up that confusion.
      
      Most Utah-copyrighted files in the Emulab source tree are distributed
      under the terms of the Affero GNU General Public License, version 3
      (AGPLv3).
      
      Most Utah-copyrighted files related to ProtoGENI are distributed under
      the terms of the GENI Public License, which is a BSD-like open-source
      license.
      
      Some Utah-copyrighted files in the Emulab source tree are distributed
      under the terms of the GNU Lesser General Public License, version 2.1
      (LGPL).

      Power "saving" additions from Barry Trent, who got them from Kevin · 03478fb9
      Leigh Stoller authored
      Lahey.
      
      Power saving turns off nodes that have been sitting in PXEWAIT (and
      are thus free) for more then a set amount of time (see sitevar
      general/idlepower_idletime, which defaults to 3600 seconds).
      
      The driver script is tbsetup/idlepower.in and needs to be added to
      /etc/crontab at sites that want to do this. Even so, operation is
      enabled by the sitevar general/idlepower_enable. Each time it runs, it
      checks for nodes that need to be turned off, and then calls power.
      Note: This should be a daemon not a cron job.
      
      To be considered for power saving, you must add an attribute to the
      node_type_attributes table called 'idlepower_enable', set to 1.
      
      Locally, I hacked up stated and power to make the state transitions
      legal so that stated does not whine. I added POWEROFF as a valid
      transition from any state, to opmodes NORMAL, NORMALv1, and NORMALv2.
      Barry's original patch already had a state transition for PXEKERNEL.
      In power, I added code to look at the actual operation, and in the
      case of "on", do not send an event if the node is not in POWEROFF,
      since a user can foolishly say power on anytime, and the node is on
      nothing is every going to change, and the state transition would be
      wrong.
      
      node_reboot takes of powering nodes on, when they are in POWEROFF.
      
      Barry on copyright issues:
       "I'm not sure those rights are mine to grant! Remember that this code
       came originally from Kevin Lahey (kml@patheticgeek.net) and
       originated at DETER (although he's apparently not there anymore). I
       don't foresee a problem from our point of view (but I'll double
       check, of course). Shall I try to contact Kevin try to sort this mess
       out, or do you think it's better to coordinate from your end?"
