Hi,

Reading it again I see that I wasn't very clear with the explanation,
sorry about that.

I didn't mean that Cinder would clean up the directory on start,
because, like you say, this may be shared with other services.

What I meant to say (but didn't) is that the installer (for example
TripleO or openstack-ansible) should create a service unit that executes
on start and removes all the contents of the file lock directory, and
makes all the other OpenStack services dependent on this one.

That way we can be sure that we are cleaning up the directory before any
service has the opportunity to start using it.

Cheers,
Gorka.
