To quote the FHS 2.0 doc: /opt - Reserved for the installation of add-on application software packages. (ie: StarOffice) /usr/local - The /usr/local hierarchy is for use by system admins when installing software locally. It may be used for programs and data that are shareable amongst a group of hosts, but not found in /usr. Typically, /usr/local will be empty after the initial install of a FHS compliant system and will remain "safe" from being over-written in the event of a base system upgrade. The FHS standard can be obtained (text, postcript and dvi formats) at : http://www.ibiblio.org/pub/Linux/docs/fhs/ or you can read it online at http://paradigm.uor.edu/linux/standard/ /usr/local and /opt are both a somewhat gray area in their implentation in that most distro's don't get their implementation "quite" right. Read the standard, check out a few distro's and you'll see what I mean. Hope it helps, Drew.
