Um, no. mount don't get the list of mounted fs's from there. mount get the
list of fs's to mount from fstab, along with default options for different
fs's to mount. There is a big difference.

However, mount have never gotten the list of mounted fs's from mtab
(or mnttab) either. That file is used by mountd to be able to report who
have mounted the exported fs's. Today that file is /var/db/mountdtab in
NetBSD. But since that is for mountd, it's on the server side in the NFS
view, and it's updated through rpc from umount. And that file is just for
information, and often contain inaccurate information anyway.

But that won't help, since it is umount that can't match up a file system
mounted that ends with a slash. (Oh, and I would think that mount gets the
list of mounted fs's from the kernel).

Good suggestion. Let us know how it works out.
