Hi again,
this might be a valid issue, but given what you want to achieve doesn't seem to be of interest of the majority of Ubuntu users. As is I have to beg your pardon and this can only be wishlist prio IMHO.
That means if you do the work and present a well rounded and tested
patch one probably will look at review&sponsoring, but it is unlikely to
find someone working on it a long time unless we identify it is more
important.
This "HP ThinPro 7.1" POV might even be that they want to avoid it would
work.
I'm unsure, it sounds more like a service request than a classic "bug"
to me.

Title:
(Ubuntu 16.04) automount 5.1.1 hardcoding libraries
Status in autofs package in Ubuntu:
Confirmed
Bug description:
Unable to use ld.conf methods (LD_LIBRARY_PATH, LD_PRELOAD) to locate
modules.
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.
Source Package:
* http://archive.ubuntu.com/ubuntu/pool/main/a/autofs/autofs_5.1.1.orig.tar.gz
* http://archive.ubuntu.com/ubuntu/pool/main/a/autofs/autofs_5.1.1-1ubuntu3.debian.tar.xz
Release:
Description: ThinPro 7.1.0
Release: 7.1.0
Binary Package:
Package: autofs (5.1.1-1ubuntu3) autofs_5.1.1-1ubuntu3_amd64.deb
* http://de.archive.ubuntu.com/ubuntu/pool/main/a/autofs/autofs_5.1.1-1ubuntu3_amd64.deb
Expected Behaviour:
Setting LD_LIBRARY_PATH=/media/GenericFlash_sdb1/usr/lib/x86_64-linux-gnu/autofs
overriding compiled location of modules so that automount works correctly.
Actual Behaviour:
automount fails to find its modules:
Code:
# /media/GenericFlash_sdb1/usr/sbin/automount -V
Linux automount version 5.1.1
Directories:
config dir: /etc/default
maps dir: /etc
modules dir: /usr/lib/x86_64-linux-gnu/autofs

Resolution Requested:
If this cannot be accepted as a bug, pointers to a work around given restrictions placed by HP and that all Linux machines here are thin clients and not development environments.
Thank you.
