Comment 13 for bug 329580

======================================================================================
MODIFIED SOLUTION: (needed because 'sdist' still cannot create empty directories after 8 years of bugs on this!!!)
This affected the 'var' empty directories and so what we do now is just check/create them in a %post section in SPEC file.
NEW SET OF FILES AND PATCHES FOLLOW.
======================================================================================

=================================================
add the following files to your tree (contents are posted above):
etc/openerp-server.conf
etc/init.d/openerp-server
etc/logrotate.d/openerp-server

=================================================
add the following lines to MANIFEST.in:
recursive-include etc *

=================================================
add the following line after the existing 'sed' line in rpminstall_sh.txt:
sed "s!^\(/etc/.*\)!%config(noreplace) \1!" -i INSTALLED_FILES

%post
[ ! -e /var/log/openerp ] && mkdir -p /var/log/openerp
[ ! -e /var/spool/openerp ] && mkdir -p /var/spool/openerp

=================================================
add the following lines to setup.py in data_files() at about line 103:
        config_directory = opj('/etc')
        files.append((config_directory, [f for f in glob.glob('etc/*') if os.path.isfile(f)]))

        config_directory = opj('/etc', 'logrotate.d')
        files.append((config_directory, [f for f in glob.glob('etc/logrotate.d/*') if os.path.isfile(f)]))

        config_directory = opj('/etc', 'init.d')
        files.append((config_directory, [f for f in glob.glob('etc/init.d/*') if os.path.isfile(f)]))

=================================================
end

PS. retested and upgraded RPM and everything worked fine.
