Heads Up! Stretch RC4 non-free netinstall iso has no non-free firmware.

Stretch-RC4-non-free-netinstall-iso has no non-free firmware, nor is it installing contrib. Both contrib and non-free are missing for main sources. Also I found the regions messed up/incorrect and corrected them in systemsettings.

No problems with RC3-non-free-netinstall-iso so use it if you are doing an install.
