This is a point for NetBSD, at my first thought. /usr/local sucks.
(You can safely skip two line below.)
Why separating "distro"-installed packages with user-installed packages?
They are just packages that are not necessary for the system to boot up.

Skipped over the pain installing NetBSD, I found that there is no
/usr/local, but /usr/pkg with the identical directory structure !!!

Will it worth mentioning?
