- Resize FreeBSD to the size of the OpenStack flavor (growfs).

- Speeds up the boot process by disabling sendmail.
- Allows an user to ssh as root with a public key.
- Make ssh(1) respond faster by disabling DNS lookups.
- Enable DHCP on the vtnet(4) interface.

Note: The CLOUDWARE list has not yet been changed to include the
OpenStack target by default yet.
