Yes, I think pretty much everything in recent Linux distributions is
aimed at making it more single-user and PC-like instead of a unix
server.  Following Apple's lead, I guess. But even a single user may
need to run applications with differing requirements. Fortunately you
can still set JAVA_HOME and give a full path to either executable -
you just have to follow the weird symlinks or list the paths from the
rpm to figure out where they really put things.
