The disklabel also has the filesystem type stored in it for each
partition. The mount command can just probe that. We can add an
ioctl if necessary.
I would rather NOT try to auto-probe filesystems since different
filesystems put their volume header in different places. For example,
it is possible for both the UFS and HAMMER volume headers to be present
(I've done it), though of course only one of the two will actually be
the correct filesystem.
