Also, sync up a couple of files with 10.2.

When we split the option list, all but the first option would have a
leading space. Fortunately, "nfs" is always the first option.

We don't want to stripe an SSD in with regular HDs (specifically at
Wisconsin) when creating the LVM VG for vnodes. They are typically a
lot smaller and won't improve performance of the VG since any operation
will likely be limited by the speed of the rotating disks.

Specifically designed to avoid using root SSD on new d430 nodes.

old parents, assign was hitting a buffer overflow cause of too
many parents.

FTOS has changed from using vlan-specific ifIndexes to the more
sensible choice of vlan tags as indexes in the Q-BRIDGE-MIB tables.
However, it still uses these ifindexes in the RFC1213 and IF-MIB
mibs!  This broke the snmpit_force10 module.

cluster with super long node names.

to the mapper and then to assign.

Need to change this entirely.

Looks like we are going to want the ability to tweak vnode placement per
run rather than by building new assign binaries. So, add new '-S
balance' and '-S pack' options. I suspect it would also be useful to add
'-S spread' to try to spread vnodes out across as many hosts as
possible, some people want this when using shared hosts.

wait time to 15 minutes, but watch for progress. Any time a node changes
bump the waiting time above five minutes. Just a start point, lets
see how it goes.

big topologies.

When set, the goal is to pack vnodes as tightly as possible - that is,
to penalize wasted slots in assignments.

One downside is that this will tend to make really lopsided mappings:
eg. if you have 50 slots per pnode, and 51 vodes, you will end up
mapping 50 to one and 1 to the other.

The other downside is that I have not yet thought about how to balance
this with link weights.
