BTW, how does FUSE fs know its mountpoint?  Other than "my fs won't be
mounted other than <here> and if you mount it elsewhere, it's your problem"
I don't see any possible way to do that...  Note that no information about
the intended mountpoint reaches fuse_mount() (and it would've been
useless there anyway, since mountpoint can change at literally zero
notice, so the userland side of FUSE would have no use for it), which
leaves only the apriori knowledge ("my code assumes that it'll be mounted
here, violate that assumption at your peril")...
