Wow - that really rocks. I just setup a mysql instance and two
wordpress app servers on my netbook (!) with 5 juju commands
Just notes for things that went unexpectedly:
1) I wasn't able to bootstrap at first, but then read from an irc log
that I needed to reboot my machine after installing lxc 
2) I tried *not* installing zookeeper initially (just
libzookeeper-java) as above, but bootstrap still exited telling me to
3) After deploying, I'd thought something was wrong because the units
were all state==null for 20mins or so until the lxc was setup (first
time on my netbook). Is it possible to show in the state that it is
being setup rather than state==null?
Thanks for the great work!
