A good example of how to use vn or slices? :-) I'm going to copy and
modify it for real disk devices. I forgot to say:
o Use option TEST_LABELLING to enable slices and labels in vn.
o Expect a lot of kernel printfs for botched and old labels.
o You can put BSD partitions on slices vn0s[1-4]. MAKEDEV has
to be changed a little to create [r]vn0s[2-4][a-h]. It
doesn't create all the partitions by default because there
would be too many.
