Public bug reported:

`juju bootstrap` succeed, but `juju status` cannot lookup bootstrap
server.

$ juju status
2012-08-29 14:16:56,186 INFO Connecting to environment...
2012-08-29 14:16:57,644 ERROR Invalid host for SSH forwarding: ssh: Could not resolve hostname node-525400720897: Name or service not known

How to reproduce:
 1. setup MAAS with maas-dhcp
 2. set "Default domain for new nodes" on MAAS settings as blank or your domain.
 3. prepare a node as "Ready" state
 4. `juju bootstrap`
 5. start the node

Expected result:
 `dig @127.0.0.1 node-525400720897` on MAAS server returns node-525400720897's IP address.

Actual result:
  `dig @127.0.0.1 node-525400720897` on MAAS server returns nothing.
 but
 `dig @127.0.0.1 ubuntu` on MAAS server returns node-525400720897's IP address.


WORKAROUND:
 clear DHCP lease table of hostname "ubuntu" forcibly *after* "Ready" state but *before* "Allocate" state.
  $ sudo sed -i -e '/\ ubuntu\ /d' /var/lib/misc/dnsmasq.leases
  $ sudo service dnsmasq restart
