BTW, I downloaded the MFSs from http://www.emulab.net/downloads/tftpboot-latest.tar.gz. And also I mounted the 6.2 freebsd.newnode and looked at the stuff inside. I found there is code related to 'role' in newclient script, but that script in 4.7 newnode do not have. Am I looked at the right place?
Well, that is definitely a screwup on our part! Sorry about that, but I guess no one has tried the 4.7 MFSs in a long time. So, I think you can grab newclient from your (src) install directory (or from the 6.2 MFS) and put it on the 4.7 MFS. Lets hope that works. Lbs
