On a fresh MicroOS installation, the create-dirs-from-rpmdb.service fails to
start:

I didn't install anything related to pcp, and could only find the following
packages being present:

* libpcp3
* libpcp_import1
* pcp-conf

The `/var/lib/pcp/` directory doesn't exist on this system. However, generating
the '/var/lib/pcp/config/' directory and restarting the service seems to
resolve the issue.
