Description

Using the packages at https://downloads.whamcloud.com/public/lustre/lustre-2.10.4/ubuntu1604/client/

1) Ubuntu has modprobe at /sbin/modprobe rather than /usr/sbin/modprobe making the supplied lnet service  ( lib/systemd/system/lnet.service  ) unworkable.

2) The share libraries for lnetctl are not shipped.

While the first issue can be worked around with an systemd override the lack of the shared library makes the service fail|
