seconds it takes the kernel to decide the other machine is not
responding (as will happens as machines are rebooting), down to 5
seconds, using a SIGARLM.

used. Add .pid file creation in /var/run to kill daemon from the new
rc.syncserver script in tmcd client code.  Add -v flag to increase
server verbosity. Add -l argument to specify where to write the log
file.

Not perfect, as it takes about 30 seconds to timeout. Need to add
a timer to it.

way to do this, but it will do. Sigh.

inconsistent DB state. One more left ... no time to mess with it right
now.

is_info table.

makefile needs to be fixed (remove fbsd/linux subdir cruft).

not rebooted or reloaded, get a reconfig instead. Currently, I check
the opmode of the node (NORMALv2), but that is horribly bogus. Need a
better way to determine that a node can be reconfiged, probably by
looking the def_boot_osid feature list. Later.

vnodes (via their pnode).

instead of rebooting. If the reconfig fails, fail through to reboot.
A reconfig will "halt" the current vnodes (or remove ones that are no
longer assigned to the node) reconfig the pnode, and then restart the
vnodes that are still assigned to the node (or create new ones for
newly assigned vnodes). A halt stops the vnode, but leaves the
vnode filesystem intact.

Not bothering to reconfig individual vnodes yet since thats pretty
much like a reboot of a vnode. Difference in time is tiny.

runtime quite a bit, because it has less scoring work to do.

Add METIS as a coarsening algorithm - we shoot for making
conglomerates of size 10.

node type, but allow it to be overridden with tb-set-jail-os().

other changes to the commvirtsig branch.

* Run assign with nice; when assign is cranking (or when two are
  cranking!) boss gets really sluggish (web, DB).

* Minor change to "impotent" option; run a little longer and print out
  what the vlan table would look like.

* Two trivial grammer changes.

parser with new functions tb-set-jail-os() and tb-set-delay-os()).
Prefer these over anything in the node_types table. Makes it easier to
test new images in the various configurations.

jail and delay node OSIDs. When set, will override anything in the
node_types table. Use with caution.

for the experiments table.

paper effort. Note, not an osid, but an osname like we specify for a
virt_node. Lookup rules are the same; first check the current project
for a match, and then check emulab-ops.

Modified routecalc, adding a command line option to dump all route lengths to a file for statistical analysis.

is broken right now.

Told Jon I'd do this so that he can check in - so that we have
snapshots of his code, but he doesn't have to worry about breaking
the build (yet.)

anyway, so not as important anymore.

from one pnode to another during a swapmod.

From the code:
        # N.B. privnet is setup first even before the default route.
        # This is because the gateway for the default route is on the
        # privnet, but our control net interface is not (because it has
        # a 255.255.255.255 netmask by virtue of being an alias on the
        # real control interface).  Thus there is no way to use the
        # default route until the privnet route is up (ARP complains
        # about "host is not on local network").

in find_best_link(), don't try plinks that already have a non-emulated
link on them, when we're doing an emulated link.
