1.6.0 Sierra RC1 - Successful install, required reboot

I've successfully installed the new 1.6.0 Sierra RC1.pkg over an existing 1.5.2 dmg installation. Only issue was that the installer failed with being unable to load kexts, but following a reboot after first running, I was able to rerun the installer and complete the installation. Further reports as I turn anything else up. SIP disabled.
Cheers and thanks for all your hard work people! Much appreciated as ever.
