Public bug reported:
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

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.
