New Revision: 310047
URL: https://svnweb.freebsd.org/changeset/base/310047
Log:
- 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.
