I wonder if people have tried going from 14-STABLE to 15-STABLE, so many base binaries dying due to not linking to the new libraries:
# /usr/sbin/pkg
ld-elf.so.1: Shared object "libutil.so.9" not found, required by "pkg"
Was saved by pkg-static and then installing compat14x-amd64.
But upgrading from source via Handbook's documented routine (including make delete-old) did NOT work. And this used to work across major versions in the past.
