of reboot since otherwise the domU just reboots and keeps running.

they do not have to be created at swapin. This is mostly for the
tutorial sessions, where we have dozens of containers launching
at the same time.

Works a lot better!

Cleanup the tmcc proxy startup and teardown.

file so that command line arguments overrides, as it does for
other options.

otherwise we just keep going and going and going.

Helps with debugging of lost state events. Also nit: fix the tmcd makefile
so it would correctly build the bootinfo modules if we make in the tmcd
directory before the pxe directory.

Due to a race with collecting events, it looks like some events will still
slip through the crack and we might wind up having missed a transition after
five minutes. If we see that we are already in RELOADING (the state transition
we are looking for) when we would declare the node wedged, then fake the
transition and continue.

I suspect this would not happen if I just looped on event_poll til there
were no more events, but I am afraid of letting that loop go unbounded.
So til I gather more data, lets go with this hack check.

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).

Previously, we were not doing this if there was a DHCP subboss (which,
in theory, should make the next-server line unnecessary since the client
should ignore us entirely). I have a vague recollection of some PXE caching
the wrong next-server value and this seemed to help at PRObE.

event_poll will trigger at most one event, so we have to loop calling it
to pick up all events in a timely manner.

Also add a couple more timestamps and debug messages.

This happens at PRObE with very large experiment swapins (500+ nodes).
Don't know why it happens, but ingoring it is safe.

Sigh...yet another change. This one is not critical, so I didn't remake
the MFSes yet again.

"62" and "47" are now in the legacy tarball and may or may not work.

Left it in for newnode MFS since even with subbosses, newnodes really
need to talk to boss.

I am not 100% sure this is correct, but if not correct, it is at least
no more wrong than the old code!

In particular, need to pass in a base multicast address for the null config
so we don't have to recompile on each subboss.

portstats shows ports in a syntax that it doesn't accept as input;
i.e., "node:card.port".

when inner boss is not responding yet.

The call from suexec appears to turn extra spaces at the end of the
command line, into an extra argument. Ick.

2. convertPortFormat now support LACP port-channel index, which is:
   - for IfIndex: 1000000 + (port-channel#)
   - for Port class: card is 1000 and port is port-channel#
   - for Sysdb: Port-ChannelX, where X is port-channel#

3. setVlanIfOnTrunk doesn't need change since convertPortFormat can
   deal with port-channel index.

4. LACP port-channel is treated almost all the same as normal port by
   Arista Python API when doing VLAN operations, so all VLAN ops can work
   with port-channel without needs of change.

5. The last, but most important, I don't have an active and workable
   physical port-channel to test on, so for now, let's just pray...

New option -s datetime to specify a starting time for the pre-reserve.
New option -e datetime to specify a ending time for the pre-reserve.

The idea is that you can schedule a pre-reserve to begin sometime later,
and you can optionally specify a time for a prereserve to terminate.
There is a new script that runs from cron that checks for pre-reserves
that need to be started or terminated.

For example:

boss> wap prereserve -s '2012-09-14 09:08:15' -e '2012-09-15' emulab-ops 50

You can use any datetime string that is valid for str2time. At some point
it would be nice to allow natural language dates ("tomorrow") but that
requires a another bunch of perl packages and I didn't want to bother.

NOTE: when using -e, -r is implied; in other words, when the
pre-reserve is terminated, the table entry is cleared *and* the
reserved_pid of all of the nodes is cleared. Any experiments using
those nodes is left alone, although if the user does a swapmod, they
could easily lose the nodes if another pre-reserve is set up that
promises those nodes to another project.

When deleting, remove node_activity and other slothd slots.
Going to have slothd start reporting for individual VMs soon.
