running the watchdog. At some point I'll come back and convert to
watchdog for all the nodes.

1) Add support for local jailed nodes. This support overlaps in a nasty way
   with remote jailed nodes, but I added this for testing purposes, and as
   it turns out its pretty handy. A second pass is needed to unify remote
   and local jails, but for now this is how it goes:

  	tb-set-hardware $node3  pc600
  	tb-set-hardware $nodev1 pcvm600
  	tb-fix-node $nodev1 $node3

  So, "fix" $nodev1 to $node3. The intent is that once $node3 is
  allocated by assign to a real testbed node, we can then allocate a
  virtual node on pcXX to $nodev1. I did this primarily to allow for
  easy testing of jails via my NS file, without having to hack assign
  wrapper too deeply. So, after assign runs, I use avail to get the
  available vnodes on the assigned pcXX, allocate those for the virtual
  nodes. At present, we still depend on pre-exsiting pcvm nodes for each
  real node.

2) Add code to assign non-overlapping port ranges to each experiment. This
   could be moved to an external script, but is fine right here. There is
   an ipport_ranges table for determining a testbed wide range (currently
   256 ports). This is of course only meaningful when using jailed nodes,
   so do not bother to set a range (and use up the port space) if no jailed
   (virtual) nodes.

the main tree. Note that this hack should be generalized (as we have
discussed many times).

created by libsetup are now created in /var/emulab/boot; nothing is
written into /etc/emulab or /usr/local/etc/emulab anymore. This was
a requirement for jails, but is also a good thing to do anyway.
There are a number of jail config changes to support the old vnodes
and the new style jail vnodes; specifically, a setup routine to called
from inside the jail when it first boots up to the get the usual
assortmant of config info from tmcd. Also Merge local and remote
update routines into one. Other various little changes for SFS and the
MFS.

working in our images, damn it!

"hash" has been renamed as "key."  V2 also eliminates the 666 length check.

When an image is created successfully, a message stating this fact is printed
to the log.

More importantly, I fixed a bug in the NFS slack factor logic which resulted
in create_image waiting forever for progress to be made.

Also print out the fixed nodes when a virtual node is fixed to a
NS node. Reflects a change in the front end parser.

nodes, so path is consistent).
Also add jail support by looking to see if the node is a jailed node,
and passing that to the client side in the form of a -j option.

replace it eventually). Like the ron nodes, local nodes will now
periodically (once every 5 minutes) send a udp packet to boss to
indicate the node is alive and to see if it needs to check for account
updates. This will replace the once every 5 minute fping we do from
db/node_status (once I whack that script), and will simplify the
existing problem of propogating accounts to nodes (nodes down, nodes
in the swapping phase, etc).

bunch of relocations of things from /etc/testbed in the old world, to
/usr/local/etc/emulab in the new world. Basically, /etc/emulab has
just a few config files that do not change. All of the binaries and
scripts are now placed in /usr/local/etc/emulab, and *all* of the
variable stuff that was written into /etc/testbed is now written into
/var/emulab/{boot,logs,jails,lock,db}.
