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.
