Does it really matter to disklabel whether I specify 'disklabel -r -e wd0s4' or 'disklabel -e -r wd0s4' on the command line? Why can't I edit those values? I'm root, dammit, I can do whatever I want! ;) BTW, I did reboot the machine and the disklabel from wd0s4 had been cleaned from wherever it was being read. I wrote a new one, newfs'ed the partition, and all seems well. -- Crist J.
