How can one check if a device can be safely unmounted at the moment.
Sometimes umount fails as the device is busy. Is there a way to check
if the device is busy, without unmounting? The umount manpage does not
discuss this situation.

(fuser -mv /$mnt_point) is relatively standard.

lsof is quite a bit more powerful and complete, and available for Debian.

Neither of those commands "see" NFS exports.

Dissent is patriotic, remember?
