It's just a very simple test to see if existing
directory structures can be traversed correctly,
nothing more. It's a hint to filesystem integrity.
So just a few basic tests if the mount has worked
as intended (and you have free space on the device
and there is something on it, ideally something you
_expect_ to be there).

Sorry, I am old and stupid. Very stupid.

	fuse_load="YES" ---> /boot/loader.conf

	fusefs_enable="YES" ---> /etc/rc.conf

Very very stupid.

The addition to /boot/loader.conf serves the same purpose
as using the kldlist="..." setting in /etc/rc.conf, except
that it happens at a much earlier stage. The result is the
same, as "kldstat" output will correctly show.

Very very _very_ stupid. ;-)
