The brief instructions I put together for developers of another
project to test on FreeBSD, on one of the snapshot VMs:

1. Log in as root on the console
2. Run "ifconfig -l" to list network interfaces The virtual nic will
likely be em0 or vtnet0 depending on the VM software.
3. Add to /etc/rc.conf (assuming vtnet0 interface here):

ifconfig_vtnet0="DHCP"
sshd_enable="YES"

4. Run pkg and answer Y to install the package management tool
5. Run pkg install git gcc gmake
6. Run adduser to create a user account
7. Run shutdown -r now to reboot
8. ssh to the VM as your user account

I included gcc in the pkg command above but you can leave it out and
just use the Clang in the base system. The brief experimentation I've
done with toybox is on FreeBSD 10, with Clang 3.4.1. If you use a
FreeBSD 11 snapshot from the link above you'll have Clang 3.8.
