NTAC:4UC-11

Christian, thanks so unless I work-out how I've seemingly mangled
Libraries, I may have to be asking HP for a bye.  Igel builds-in
NFS support and provides config of the required shares using its
GUI.  Not sure why HP chose to leave it out.

Kind regards,

M

Subject: [EXT] [Bug 1891551] Re: (Ubuntu 16.04) automount 5.1.1
hardcoding libraries

This email originated from outside the organization.  Do not click links
or open attachments unless you have verified this email is legitimate.

Also you reported this against v5.1.1 which is xenial, such a change
could have rather unclear impacts which means it would only be
implemented going forward (20.10 or later) but not back in 16.04 which
your system is based on.

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.

  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

  Compile options:
    ENABLE_FORCED_SHUTDOWN ENABLE_IGNORE_BUSY_MOUNTS WITH_HESIOD
    WITH_LDAP WITH_SASL LIBXML2_WORKAROUND

  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.
