given the recurrence of opt/ related posts, it might be appropriate to
provide an other-distro-refugee howto  on debian.org, or, at least, a
specifically new user link to fhs resources. as far as i know, the only
linux distro that automatically assigns and relies on opt/ is suse (last
experience, 8.0; rh 5.0). 3 days of mandrake left me with only a memory
of sheer frustration, so much so that i simply can't remember whether
opt/ was a part of their plan. i know that opt/ is/was a feature of
various *nixes, but i can't see where /usr/local doesn't serve the same
objective already.
