[Systems] a.sl.o progress

[David Farning]

We are having a productive week here in Bolzano!

Dogi and I have separated off form the others to work on a.sl.o.  Dogi
and Bernie have been setting up vm templates so we can abstract out
the various a.sl.o components onto individual VMs.  I think these vms
are currently living on treehouse.  Long term the big wins of this
approach with be that we can:
1. Individually tune the components.  Because of the numerous systems
interacting on sunjammer I have been having trouble determining the
meaning of benchmarks.
2. We will be able to move the vms onto seperate physical machines as necessary.
3. There is no direct interaction between the aslo cluster and
sunjammer.  Rather than setting up nfs between download.sl.o and
sunjammer, I am running rsync every ten minutes.  If sunjammer is
compromised it will not affect aslo.

So far we have a test instance running at
http://140.186.70.144/en-US/sugar/ .  Below is to do list for the rest
of the week:)   It looks like it will continue to be a rather
iterative process.  I hope we can finish setting it up this week.
Benchmark and test it next week.  And go live the following week.
