This way, we only load the modules that will actually get used,
so modules (like the apcon module) that have other dependencies
won't mess people up.

That file is used to build the Linux MFS version of frisbee.
Also cranked up the allowed bandwidth from subboss (config_null).

be generalized in some fashion.

Change to how vlan ecapsulation links are represented in the lans
table. Formerly, we had two links; one was the underlying vlan and the
other was the ecapsulated link running over it. This is required when
*not* using vlan encapsulation since there might be multiple emulated
networks on top of the vlan network.

However, when using vlan ecapsulation, this strictly one to one; there
are multiple vlan links, with the ports in trunk mode. There is no
reason to have two entries in the lans table, and in fact was causing
me grief wrt vlan tag reservations in protogeni, since the name of
link is not the same as the name of the underlying vlan link that was
getting created. And so it was impossible to match up the
reservations.

I pray this does not break 10 other things.

we can multiplex vlans across the backbone link.

one.

Takes care of downloading the update tarfile, mounting the MFS and
installing the tarfile.

Right now, this is pretty specific to updating the frisbee MFS.
It should be generalized to the other MFSes and, to the extent it makes
sense, reconciled with the existing update mechanism.

and a linkname.

It was possible for an experiment to crash stated simply by registering
the wrong node as an emulab_syncd.

requires a fully bound rspec; the other side can be left unbound, as
long as you say what CM. Each side will contact the other side to find
out the bound details.

"testing" variable, which of course, makes things break in totally
obscure ways.

No need to suck in an extra library.

It should not be necessary to do anything to you inner elab infrastructure
to make it work in the New World.  Eventually, those with elabinelabs should
update/rebuild/install their Emulab software on boss/ops and update their
MFSes so they too will use a master server.

reason I totally forgot to make it conditional. Sheesh.
