The online FreeBSD bsdlabel man page is online at http://www.freebsd.org/cgi/man.cgi?query=bsdlabel&apropos=0&sektion=0&manpath=FreeBSD+9.0-RELEASE&arch=default&format=html One example given is This is an example disk label that uses some of the new partition size types such as %, M, G, and *, which could be used as a source file for ``bsdlabel -R ad0s1 new_label_file'': # /dev/ad0s1: 8 partitions: # size offset fstype [fsize bsize bps/cpg] a: 400M 16 4.2BSD 4096 16384 75 # (Cyl. 0 - 812*) b: 1G * swap c: * * unused e: 204800 * 4.2BSD f: 5g * 4.2BSD g: * * 4.2BSD but you would have to replace the * with actual appropriate numbers. After you install the disklabel, you could mount each data partition, but not the swap partition, to see if the directory and file structure looks right. Tom
