I don't think so. You already need the / filesystem, and with today storage sizes, if you can hold that, you can hold the whole system, period. Even on any embedded that can run Debian. The last time I've seen a split done due to small / was Maemo ten years ago. And guess what? They didn't use / vs /usr but hacked something where both / and /usr were on the small mmc while big /opt hold most of the files, with symlinks from /usr. That's because their needs were different from those of Ken Thompson in 1971. A reasonable and often important split is keeping /+/usr apart from a box's main purpose, be it /home, /srv or /var/lib/postgresql -- but in any case both / and /usr will be on the same filesystem. Thus, I'd say /usr is pointless on any machine we can reasonably support. -- A tit a day keeps the vet away.
