experiment. Here is mail to tbops:

* Moved the working directory for experiment setup/swap/end to a new
  directory located on boss instead of over NFS to /proj/$pid/$eid. This
  new location is /usr/testbed/expwork/$pid/$eid.

* Changed the name of the directories we create in /usr/testbed/expinfo to
  $pid-$eid.$index where $index is a new autoincrement field in the DB
  table. I really hated the names that were created before.

* Changed where logs are written from /tmp to the new location in
  /usr/testbed/expwork/$pid/$eid.

Okay, why.

* We no longer operate on NFS mounted directories that might hang. Its
  easier to catch the situation where a copy of the log file over at the
  end of experiment creation fails cause of an NFS problem.

* We no longer have user writable files that are inputs to other parts of
  the system (like top and ptop files).  Not that a user would be bad, but
  it closes a hole.

* We no longer copy user writable files from /proj to boss where we might
  fill up an important filesystem cause the user put a .ndz file in the the
  working directory. Not that a user would be bad, but it closes a hole.

* Its easier to save all the log files this way, for each swap in and
  out.

* Removing a directory over NFS is a royal irritant when someone is CD'ed
  into that directory or looking at a file on the other side (the astute
  observer will peg this as the reason I went down this idiotic path in the
  first place!).

* About 6 other reasons that I can no longer remember. Seriously, I really
  had more reasons I can no longer remember! :-)

the testbed list.

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.
