as a small aside; after being corrected a few times on bbs, i now know
that

  pacman -Qqe | grep -vx "$(pacman -Qqm)" > pkg.list

and

  cat pkg.list | xargs pacman -S --noconfirm --needed

work the best for this.  list out only explicitly installed minus any foreign
packages; then only install those that are needed (pull in your own
deps).
