Late breaking updates to local provider.
zookeeperd isn't required anymore, libzookeeper-java suffices and saves an extra
ppa version needed is revno 388
working config example snippet for a local provider
please note, that using /tmp for a data-dir won't survive reboots. the
environment will need to be destroyed and bootstrap unless a more permanent
location is chosen.
we're looking into issue for some where plymouth --ping hangs at boot in the
