Wrap all calls to XMLin/XMLout in eval since on error they call die(),
and we don't like that.

node_hostkeys.  tpmblob uses 'tpmblob' and tpmpubkey uses 'tpmx509'.

its a delay node.

among all switches in a stack.  Does check to see if the required additional
perl modules are installed and will revert to standard behavior if not there.

Currently only looking up vlan numbers from all the switches in the stack
is actually parallelized; this alone results in a speed up by a factor of 5
on DETER.

Additional speedups could be gained if we assign all the vlan numbers for
vlans in snmpit -t at the time it is run thereby allowing us to
construct different vlans in different switches in an overlapping way.

We haven't implemented this yet on DETER awaiting synchronizing with the
mothership to make use of VLan->setVlanTag().

handle quieting backends in a different way - (to minimized changes
to nortel, foundry, and hp support), use perl "select" with one arg
to change default for "print" with no explicit fileglob.

print STDERR, STDOUT, still works; won't interfere with tblog() and friends.
will put parallization mods in a separate CVS change.

are present, prefer to use the URN.

Changed rc.linux to support sharing swap space with FreeBSD, since
newer FreeBSD images want to do this.

On first boot, all swap entries are removed from /etc/fstab to ensure
no invalid entries are present.  Then the root disk is scanned and any
type 0x82 partitions are added to fstab as swap devices.  An empty file
is created in BOOTDIR once complete, indicating to subsequent runs that
this step has already been done.

On each boot, the swap entries in fstab are checked.  If the device
listed is a valid block device and is not currently active, mkswap and
swapon are run to activate it.  Entries that have the "noauto" option
are skipped, as are ones prefixed with `#'.

Also create var/emulab/boot in the guest -- this should make it possible
to boot any fedora-like guest image, even if it hasn't been emulabized.
However, we need to also add support for the debian way of configuring
interfaces...

Clean up a couple of minor inconsistancies in the modules concerning
printing ports not in the wires table and make sure utterances like
"wap snmpit -i Nortel10 4/4" work properly.

- Keep from looping forever if we don't get loadinfo data
- Fix zapsuperblocks; make it use files under /sys instead of calling
  /sbin/fdisk (I long ago gave up trying to make rc.frisbee compatible
  with both FreeBSD and Linux).

Added code to create www/crossdomain.xml and www/protogeni/crossdomain.xml. The former allows flash clients to use the latter. The latter allows flash clients to access the xmlrpc interface if they hail from boss, ops or *.protogeni.net

Whenever making an xmlrpc call to a new site, make sure to check the protogeni/crossdomain.xml (if it exists) rather than the root crossdomain.xml

ever use one of the pseudo partitions linux creates when it sees a bsd
disklabel.

(slices suck!)

post facto.

because we (vnode_setup) needs to go out to the nodes and run vnodesetup
to trigger the reload, but os_setup needs to setup the reload.  So for
now, os_setup sets up the reload but does not wait nor reboot the vnode;
vnode_setup does that like normal.  Probably there are going to be timeout
problems, but it's good enough for my needs right now.
