>Description:
On a drive using DOS partitioning, dscheck() prevents overwriting the
first 1K of a partition that formerly held a UFS filesystem, even if
the partition type is changed to something other than DOSPTYP_386BSD.
>How-To-Repeat:
dd if=/dev/zero of=/dev/rwd0s2 bs=512 count=1
>Fix:
Ignore contents of non-BSD partitions.  Don't even call
readdisklabel().
