Glad it works.

There's not a single right procedure, it's very much
platform/distribution-dependent.
Probably, it would be better to check the documentation of your
platform/distribution/whatever or ask their packagers.

The same applies here.

I would also recommend testing the shutdown procedure and making sure
that everything works as expected on power failures.
Please, let us know the results of these tests, so that we can add a
more informed report about your device to our library
