Hello, a forwarded bug: It would be nice if there were a link in SEE ALSO to smbumount. It's obvious in retrospect how one should unmount file systems which were mounted with smbmount, but it would still be helpful. (It's mentioned in the AUTHOR section but that's hardly where you'd look for it. The smbumount manual page already has a link back to smbmount.)
Fixed. - John T.
