It is site-local as opposed to common to the distro. The FHS has this to say about it: /usr/local : Local hierarchy Purpose The /usr/local hierarchy is for use by the system administrator when installing software locally. It needs to be safe from being overwritten when the system software is updated. It may be used for programs and data that are shareable amongst a group of hosts, but not found in /usr. Locally installed software must be placed within /usr/local rather than /usr unless it is being installed to replace or upgrade software in /usr. [27] [27] Software placed in / or /usr may be overwritten by system upgrades (though we recommend that distributions do not overwrite data in /etc under these circumstances). For this reason, local software must not be placed outside of /usr/local without good reason. I use the FHS as a reference, because the Major (GNU/)Linux Distributions use it as a basis. I could not find any history being mentioned in Google, the FHS, and I could not find an old copy of the FSSTND (the predecessor to FHS). I had always known and seen /usr/local as being site-wide per architecture. > /usr/local came out of the need for computer-specific software > installed when /usr was, indeed, mounted from a central NFS server. Those days are pretty much over. Is your home directory still in /export/home? -john -- [email protected] http://www.kernel-panic.org/cgi-bin/mailman/listinfo/kplug-list
