I might be mistaken here as I tried that in May, when I upgraded my 
production server to 7.2; I probably tried using the 'label' subcommand 
or it wouldn't show up on boot, right? (There was a mistype in my 
earlier message; should be "label for provider ad0s1b is label/swap", 
not "ad0s1a".)

I'll check, though that'd require backing up and reformatting everything.

The problem with ufsids is that unlike a manually set label, you can't 
really distinguish between them (as opposed to the default scheme of sXY 
where for a boot device you can be almost 80% certain that ad0s1a is /, 
f is /usr, etc etc - especially if the default number of partitions was 
created).
