When doing an upgrade, freebsd-update merges your changes into the files
under /etc and stashes the merged version away to install when the time
comes. This means if you make changes between 'freebsd-update upgrade'
and the final 'freebsd-update install' these will be overwritten by the
install.

No, it wouldn't. f-u stores the files gzipped and named by hash, so
neither find nor grep -r would find anything.
