it isn't in /etc/fstab because it isn't actually mounted. The
filesystem only exists at the library level.

The main consequence of this is that:

- you can't execute programs off the /smb/ filesystem
- you can't mmap() the files

In fact, we could make it handle execution and mmap() as well, but it
would be an ugly, slow hack.
