Hiyas,
I noticed that the RPMMacros page does not mention that
%{_sharestatedir} expands to %{_prefix}/com on CentOS and probably also
RHEL:
https://fedoraproject.org/wiki/Packaging:RPMMacros
Also it would be nice to have the notes about differences in other
releases inside a admonition, to make them easier visible.
Regards
Till
