It's worse than you might think.  On OpenBSD, the line between
partition and slice that we have in FreeBSD doesn't exist.  Everything
is a partition, and they create the necessary labeling when the label
is read.  Since FreeBSD lacks that feature, for the most part, you are
going to have to implement some kind of 'file'-like magic number
recognition for filesystems if you want to use a similar approach.
