Author: rmacklem Date: Mon Apr 25 23:12:18 2011 New Revision: 221040 URL: http://svn.freebsd.org/changeset/base/221040
Log: Modify the experimental (newnfs) NFS client so that it uses the same diskless NFS root code as the regular client, which was moved to sys/nfs by r221032. This fixes the newnfs client so that it can do an NFSv3 diskless root file system.
