On recent SLES and openSUSE systems it is necessary to read the
file /lib/lsb/init-functions instead of /etc/rc.status for proper
integration with systemd. Certain implementations of killproc
need a pidfile so make sure that one gets created. Also, correct
the opensm service dependency list.

There is also an option to run opensm with ibsim. In that case neither rdma
nor openibd should run.

On opensm segfault (happens one in a while :), pidfile won't be removed, so
you won't be able to start the opensm again. I guess that same thing can
happen on warm reboot.

ibsim is unlikely to be used by end users or system administrators in a
normal startup environment. I doubt it needs to be accounted for in the
init script. Most users simply don't even know enough about ibsim to be
able to use it at all.

The stop action in the script should handle cleanup for you. If it's
called, and a pid file exists, but the pid is not running, it should
remove the pid file and the subsystem lock file so that a clean start works.

Does running opensm with ibsim require to preload libumad2sim ? If so, that's
something that's not supported by the current opensm init script, isn't it ?
If that is correct then it looks fine to me to make the dependence on the
openibd/rdma service explicit in the opensm startup script.

Hello Doug,
Do we really need the lock file ? On some Linux systems (Ubuntu) the
/var/lock/subsys directory does not even exist.

It's an old holdover from LSB compliance. *I* don't personally care one
way or another, but it's supposed to be there for ancient scripts that
look there to find out if a service is running. Probably none of those
ancient scripts look for opensm as it wasn't around back when they were
written and the "new and improved" way of checking a service in LSB is
to run the init script with the status command. But, that's why I have
it there.

Theoretically, a user can export LD_PRELOAD=libumad2sim.so prior to executing
the script. But I agree with you that it can be out of the scope of opensmd
script.

Sounds as a good direction.

* [PATCH 3/4 v2 for opensm] /etc/init.d/opensmd: Improve systemd integration

On recent SLES and openSUSE systems it is necessary to read the
file /lib/lsb/init-functions instead of /etc/rc.status for proper
integration with systemd. Certain implementations of killproc
need a pidfile so make sure that one gets created. Also, correct
the opensm service dependency list.

v2: replaced "[ -e $pidfile ]" test in start() by "[ -e $pidfile ] && [ "$(readlink "/proc/$(<$pidfile)/exe")" = "@sbindir@/opensm" ]"
