Trying to understand what bsdlabel is telling me, I did some experimenting. The computer has a working installation of Vers. 4.10 on ad1, so I booted to ad1 and ran 4.10. Using 4.10 and disklabel (replaced by bsdlabel in 5.3), I find that disklabel seems happy with my ad0 disk, as compared to what bsdlabel says about the same disk when running 5.3. Perhaps this is a problem with bsdlabel? I don't know enough about what I am seeing to suggest that, but I don't understand what bsdlabel is reporting to me. Below are outputs from disklabel and bsdlabel, reporting on the same disk. I used bsdlabel -A this time to make the displays similar. When I don't use the -A argument, I get many more lines describing problems; please refer to my November 16 message to see those lines. Help please?
