I really prefer the gpt label and I have added it, but I can't figure out how to remove the ufs label. I boot single user and run 'tunefs -L "" /dev/ada1p2' but I get an "unable to write superblock" error. This is before mounting the drive RW, but it is, of course, mounted RO. I tried setting the "allow foot-shooting" debug flag, but it did not help. Is my only hope to boot a live system? (I have no CD, so I guess I could try a a thumb drive.) -- R.
