There are similar problems in unix-based OSes, and are solved by
environment variables ($HOME, $PATH, etc).

So you can try something like this:


-- or:
-- package.path='/opt/common/lua/'..os.getenv('USER')..';'..package.path

and ask every user to put their modules in their home directories, in
~/lua or /opt/common/lua/<username>.
