* **New**
* Using a config variable, Dusty now manages how large (in megabytes) to make your vm. On each start of boot2docker, Dusty will adjust your vm's memory size.
* **Misc**
* Install script now passes -H flag to `sudo dusty -d --preflight-only`, so that `boot2docker version` won't create `~/.boot2docker` owned by root.
* We are now attempting to load the SSH_AUTH_SOCK, if it is not currently set, with each Dusty command. This fixes a race condition in launchd between Dusty and SSH_AUTH_SOCK.
