* Need a way to run an action when a property changes, but only run it once for the whole. For example, may want to restart apache, but only once despite many config changes being made to satisfy properties. onChange is a poor substitute. * --spin needs 4 ssh connections when bootstrapping a new host that does not have the git repo yet. Should be possible to get that down to 1. * Currently only Debian and derivatives are supported by most Properties. One way to improve that would be to parameterize Properties with a Distribution witness. * Display of docker container properties is a bit wonky. It always says they are unchanged even when they changed and triggered a reprovision. * Should properties be a tree rather than a list?
