hopefully get bigger and reduce the amount of typing that we all
do. I hacked up sched_reload and os_load to use it. Pretty simple to
start with.

I'm not planning to go much further on this until we sync up with the
dbtoir branch since it will just create needless branch merge errors.

Possible statuses are: "up","possbily down","down","unpingable"

"possibly down" indicates that a node has looked down for 1 run of node_status -
next time node_status is run, it will be set to 'down' if it still doesn't
respond.

"unpingable" indicates that a node is beleived to be running an OS that does
not reply to pings, so we can't tell if it's up or down

the sbin directory to set/clear the MOTD, as well as login/nologin.

replaced by the "images" table. New os_info table is added. New web
pages to add and delete OSIDs to/from the os_info table, for use in
the NS file. tb-create-os is gone. handle_os no longer operates on the
tbcmds file, and no longer writes anything into the ir file. Moved the
setting up of os state (nodes table) from os_setup to handle_os, where
it should be. os_load and sched_reload now take a single argument, the
name of the imageid from the images table.

to mere users.

machines in the experiment. exports_setup runs on paper and queries
the DB, generating a set of export lines. That is sent over to
plastic, and piped into exports_setup.proxy, which generates a new
/etc/exports file and restarts mountd. All of the client setup scripts
have been changed to mount the project and user directories.

enough nodes available to try starting an experiment.

list of nodes for console_setup to avoid an ssh per node. Change the
sleep(1) in console_setup.proxy to a select(,,,0.25). Looks to be
about .25 seconds per node now, plus a constant time of 1.5 seconds.

reset its image_id back to the DB default for that node type.

and power control sharks correctly (a shelf at a time). We also feed the
new shark names to assign in the ptop file. Showgraph was also changed
to reflect db changes.

web output friendly. Less is more.

simple autogen of the symlinks to plasticwrap on the control node, and
added control-install targets in several more directories.
