In that case you must do a longest match on the output, and make sure you
use a correct physical path (i.e. resolv all symlinks).

# realpath /opt
/usr/local/opt
# LANG=C mount | grep "on /usr/local/opt"
# LANG=C mount | grep "on /usr/local"
/dev/vg0/usr_lv on /usr/local type xfs (rw)

The point here is not to search for /opt in mount result and not to find
/usr as a first match. I am not sure if grepping for the path can be done
with a awk or sed script in a single run easyly.
