Actually it is, in both FHS version 2.3 and version 3.0. http://refspecs.linuxfoundation.org/FHS_3.0/fhs/ch04s02.html The following directories, or symbolic links to directories, are required in /usr.

When I tried to A symlink form /usr/local to a read-only AFS space is *not* the same thing as symlinks for /usr/local/bin, /usr/local/etc, /usr/local/share, /usr/local/lib, etc. Be clear that replacing /usr/local with a symlink in the form you describe is *not* compliant with the FSH. Not that it's not useful in your environment, but just so you appreciate that you may have issues with core packages such as the "filesystem" package.
