(or was it months)?

Additions for detecting when nodes are down and moving them to testbed/down expt. Sends mail if something is down, waits 2.5 minutes currently before giving up.

wait for all of them. Also protect against an ssh hang with a
surrounding alarm. Also reduce output for web page.

the testbed list.

rest to STDERR.

now, but don't actually do anything with the node. Leave that to
user to run the os_load script.

os_setup and ifc_setup read the features list from the database for
the currently assigned OS. os_setup will not enter a ping wait for the
node to come back alive if the node does not support ping! ifc_setup
will not try and and do ifconfig stuff if the OS does not support ifconfig.

via the create-os directive in the NS file.
tbsetup/ir/handle_os.tcl - Do a valid check for the image given with
	set-node-os in the NS file, and propogate that information through
        to the IR file. Nothing is added to the DB.
tbsetup/mkexpdir - Add a tftpboot to the list of experiment directories. The
	tftpd daemon now allows kernels from /proj.
tbsetup/os_setup - Very hacky changes to allow for multiboot kernels. Read
	local images table and cross check against that for nodeos spec.
        Hardwire in "mb" as a special partition tag that says to not try
	and do too much with it. This should be changed to a DB check of
	some kind. On reboot, do not wait for these nodes to come alive since
	there is no way to determine if an oskit kernel (or any foreign)
	kernel is running.

for no more replies. Still not great, and this causes the loop to reboot
all the machines to get kinda long.
More important is that we have to wait until all the nodes reboot and come
back so that the next part tbrun does not fail. That adds a bunch of time
to this. Needs to parallelize the reboot and wait, but thats too hard too
deal with right now.

next_boot_path so that OSKit-NETBOOT.SILENT does the right thing.
This gets pulled from the disk_images table. Temporary though, since
we want to allow more flexibility in how the OS and related stuff
gets specified.

appropriate for the node type). This prevents the user from editing
the IR file directly and specifying a bogus image ID.

checks to make sure that the OS image that has been specified in the
IR file is valid. Need a database check for this. Also, no delta stuff
yet; just the main OS partitions that are know to exist on the disk
already. Guess we also need to worry about reloading the disk from this
script. Sigh, still lots to do, but this will be okay for a little while.
