That's very much not true. A vnode can be created by any lookup,
which can happen in response to a bunch of system calls which will not
`open' it (such as stat(2)). I believe there is also some vnode
caching stuff in NFS's `readdir plus' RPC. And symlinks are never
actually `opened', per se.
If you mean in the more general sense of `possibly a long time, before
the current boot, possibly even by a different OS accessing the same
disk', then that's marginally true (modulo symlinks), but it's not
terribly interesting.
