Debian based distros use dhcpd3 instead of just dhcpd. Accordingly
paths to lease files etc are different as well. This patch ensures
that the test-suite can run with either dhcpd or dhcpd3.
This patch enhances nfsroot and the nfs test-suite with compatibility
for debian based distros. This is mainly the difference of using
portmap instead of rpcbind and the missing file /etc/netconfig
This implements a default path of /tftpboot/%s if no path is provided,
and adds host name substitution for %s, with a fall back to the IP address,
as provided by the kernel's nfsroot handling.
The test suite is updated to test this functionality.
Test additional combinations of command line and DHCP option formats. This
is by no means the complete list, but gets us started with some common ones.
This creates a basic root filesystem, creates an initramfs, and tries
to boot to the basic filesystem.
The init code on the test filesystem prints how much memory is used vs. free
and then drops to a shell. Exiting the shell will power off the VM.
