krpc: unbootable ZFS-on-root after major upgrade to 11.2
Hi! It was brought to my attention that 10.x did not require availability of krpc for ZFS-on-root system to be bootable but 11.x does. That is, major upgrade of 10.x ZFS-on-root system to 11.x results in non-bootable broken system if it uses custom kernel without NFS bits that automatically come with krpc, and the system was built with MODULES_OVERRIDE="zfs opensolaris" and no krpc mentioned. We could have mentioned that requrement in Release Notes but we had not. Should we issue an Errata Note?

It's kidn of strange that root-on-zfs requires krpc.> We could have mentioned that requrement in Release Notes but we had not. > > Should we issue an Errata Note?-- Andriy Gapon
