This is probably not necessary, but paranoia dictates that the actual
netroot handlers should check if all three required arguments (netif,
root, NEWROOT) are there and useable.
rpc.statd is only needed for NFSv4, because it's required for
locking. We don't support locking for NFSv2/3, so start it only
if we are mount from NFSv4.
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.
Probe for NFS and NBD capability before trying to load their modules
in case they are built into the kernel. Ugly use of flag files, but
avoids the need for grep to be on the image.
Parse and convert commandline options in the cmdline hook, and
fill in the missing pieces in the netroot hook. This also allows
root=dhcp to work as expected.
