hello,

having configured my slices not starting with slice "a" (i've tried 
putting my / on slice "e"), it appears that the boot block (serialline 
or not) cannot be installed:
i get a "device not configured" because it tries to install it on 
/dev/wd0a (which doesn't exist).
i suspect that this must be the same for netbsd-current.
i believe that the tool should use /dev/wd0d which is the whole disk.

cheers,
