Description

lnet.service which is a systemd script doesn't work as expected. There are multiple ExecStart lines, while the documentation suggests that the ExecStart lines are executed sequentially, they are in fact executed in parallel. This causes race conditions, where lnet might not be configured before trying to import the YAML config file.

It is possible to use the /usr/sbin/lnet script which already starts, stops and restarts lnet properly. This script can be called from ExecStart.
