You should be fine with that. A reasonably sane / is quite static, and /usr tends not to change all *that* much. There's some precautions I always take on server: /var, /usr/local, /opt and /tmp are separate mount points portage moves to /var, not /usr With those dealt with, the balance of / shouldn't grow much. > >> it's really easy.
