Hello,

When I was installing opennms in a clean env, I got this error:

Installing: opennms-docs-1.10.6-1 [done]
Additional rpm output:
warning: /var/cache/zypp/packages/tresc-all/noarch/opennms-docs-1.10.6-1.noarch.rpm: Header V3 DSA signature: NOKEY, key ID 5b9efd43

• making symlink for /opt/opennms/docs... ln: failed to create symbolic link `/opt/opennms/docs': No such file or directory
  done

As opennms-docs-1.10.6-1 depends on no package, it was installed first. However, it seems that some pre script tries to symlink a dir, that still does not exists before the package is installed (or when the opennms is already installed).

This is a trivial fix. The symlink could become a static file inside the package instead of being created at runtime. This way, the parent directory would be created by any opennms packages.

As workarround, just reinstalls the package after any other opennms package is already installed.
