A quickie; it can be worked in better if we want.

laptop, so something (or someone!) screwed up, so here is that change
again.

times have gotten worse since the USENIX paper.  Turns out we were operating
at lower BW than the paper (62/Mb sec vs. 70Mb) due to clock granularity.
The disk was falling idle too much.  Cranked it back up to 72Mb/sec for
"standard" (/usr/testbed) images.  Actually lowered it to about 54Mb/sec
for "user" images that have to be read across NFS (/proj).

Changes to the "auto nice daemon" so it can work better in Emulab.

  * sensors/and/GNUmakefile.in: Emulab-specific make file.  Updated to
    work with a build tree separate from the source and gave it a new
    version number. Files are installed under "/usr/testbed/" on ops.

  * sensors/and/Makefile: Add a warning that this is not the real
    makefile for us.

  * sensors/and/and-OpenBSD.c: Update to work with FreeBSD and add
    support for reporting process start time.

  * sensors/and/and-emulab.conf.in: Emulab-specific configuration,
    similar to the standard one, except it sends mail to tbops when it
    does something.

  * sensors/and/and-emulab.priorities: Emulab-specific priorities
    database. It excludes daemon pseudo users and the event-scheduler,
    otherwise, niceness levels apply to everyone.

  * sensors/and/and.8.man: Add the pid file to the 'FILES' section.

  * sensors/and/and.c: Added support for running a command when a
    niceness level change occurs.  Also writes out the pid file when
    not running in test mode.

  * sensors/and/and.conf.5.man: Add docs for the level commands.

  * sensors/and/and.h: Add start time and child CPU time to the
    and_procent struct.

  * sensors/and/and.startup: Changed to use "test" instead of bash
    syntax and the pid file is now used instead of killall.  Also
    added a "reconfig" option that HUPs the daemon.

experiment, and not count its pnodes or duration as if it was swapped
in! Thanks Kirk.

The actual fix is simple. The script to fix up the existing stats
records was a bear and took me all morning to get right! Even so, its
probably no perfect, but close enough. That script in the sql directory
and mentioned in doc/UPDATING.

Don't define it for frisbee.

Comment out ORBIT.  Reality treatment for some others.

script to avoid vis-ing parents of subnodes (ie. to avoid vis-ing
the PC hosting an IXP.) However, this was preventing us from vis-ing
fixed nodes at all.

 . Bump the tmcd version to 21, since this induces an incompatibility.
 . Fix the $ anchored CREATOR= pattern in common/config/rc.misc that
   forced the version bump.

the embedded BIOS disk number in sector addresses.  So you still cannot
create an image on disk 0 and load it on disk 1.

No. Really.

reassigned to a new virtual node.  We do this for every vnode, both inside
and outside the jail.

option was given (as is when called from experiment page). This
restricts the nodes to just those in the experiment.

This interacts with ghosting mode (where other nodes on other floors
are shown). In the above case, should ghosting show all nodes on other
floors, or just nodes in the experiment on other floors? For now, it
does the latter, but it might useful to have a mode for the other
case?

2. Collect up all the failed nodes and just send one mail message.

This way we know "who done it" so we can smack em around if they nfree
something they should not have.

"anchored" (^xxx$) then force it to be anchored by wrapping it.

query that maps the peer IP to a node in the DB). This was primarily
used as a safety to make sure that the node_types entry really did
match (in case the luser picked experimental addresses that conflicted
with real testbed addresses?), but not sure this test really
mattered. But, just to be safe, I changed it so that we check for a
matching IP and role='ctrl'.
