  For my part, /var/db/pkg is mostly just a reference to my local
poudriere package stash and is relevant to the BE (but pretty stagnant
unless I'm changing major versions between 12/13/14).  On my system,
/var/db is part of /.

  i don't have any custom settings in /var/db/ports, I keep all of that
in /etc/make.conf where I can splat that around easily and of course
that then stays synced with the BE.

  I'd be a little leery of having /usr/local decoupled from the BE,
but that's mostly worried about things like kernel drivers that would
get out of sync with the kernel in the BE.

  IMHO, you really do want /var/db/etcupdate synced with the BE.  My
/var/(mail|tmp|crash|log) are separate though.
