it wasn't displayed on the mere-user form, it isn't in the form data
sent back, so it looks like they're turning it off.

desire for 'hosts-<type>', where <type> is the type of its child node.
This helps assign, because it can now limit the number of places to
try assigning the host, and it means that we can give the hosts this
feature, so that they don't get used for other purposes. For example,
we can give the IXP-hosting nodes the feature 'hosts-ixp-bv' with
weight 1, and they will never get used for anything but IXP hosting.

This means that the node_type_features (or just node_features) table
must now have hosts-<type> entires to work correctly.

put:
$node add-desire desire weight

This will end up in the virt_node_desires table. assign_wrapper now
puts the desires from this table into the top file.

In particular, this keeps the ixp host nodes from showing up.

killvserver() and getanyppid() which caused vnodesetup to fail when it
shouldn't have.

We have talked about these in the past, and I just happened to be thinking
about it this morning.

trying to bring them back from the dead periodically by trying to
instantiate a vserver/vnode on them, and then tearing it down. If we
can do that, then the node is usable, and it gets moved back into the
normal holding experiment so that ptopgen will add it to ptop files.

This deamon is not turned on yet; waiting for other little bits and
pieces to be done.

There is an equiv change in os_setup that moves physnodes into hwdown
when a setup on a vnode fails.

assign can attempt to spread an experimenter's nodes across sites.

tmcd (which is bad, since tying up the tmcd threads blocks all nodes
in the testbed). The old functionality is left in tmcd for now.

On the server side, a new web page (www/spewrpmtar.php3) receives a
request for a file, along with the nodeid (pcXXX) making the request,
and the secret key that is generated for each new experiment and
transfered to the node via tmcd. If the key matches, the operation is
handed off to tbsetup/spewrpmtar.in which verifies that the file is in
the list of rpm/tar files for that node, and then spits it out to
stdout. The web page uses fpassthru() to send the file out to the
client. The client is using wget, and is required to use https (the
web page checks).

At present, the external script is run as the creator of the
experiment, and gid of the experiment. Perhaps this is not a good
idea. In any event, the file must be in the list of rpm/tarfiles,
either owned by the experiment creator or with a group of the
experiment, and the file must reside in either /proj or /groups.
I use the realpath() function to make sure there are no symlink tricks
pointing to outside those filesystems. I use the standard NFS read goo to
prevent transient mount problems that we all know and love.
