Context: HP ThinPro 7.1 Service Pack 8 (latest) is still based on Ubuntu 16.04 LTS Use Case: Thin Client -- HP will not allow Customers to install anything to OS partition, e.g. to /usr. automount installed from Canonical's repository but to /usr on a flash drive e.g. /media/GenericFlash_sdb1/usr the string: /usr/lib/x86_64-linux-gnu/autofs appears in the binary. automount does not search /media/GenericFlash_sdb1/usr defined with LD_LIBRARY_PATH.
