While working on puppet-neutron, i discovered that puppet-neutron depends on the sysctl puppet module[1] which is GPLv2 (be careful to not confuse it with another sysctl module[2] which is apache2). This dependency has been added a long time ago (in juno or before).

It seems we have a license issue (ie: apache2 code depends on GPLv2 code)?
