Pyramid has been using conditional symbolic links for years. This is
neatly integrated into Pyramid's OSx to support transparently the
two universes - ATT and UCB.
For example if you type     cd /bin
you end up in /.attbin if your universe is ATT at this point of time
or in /.ucbbin if your universe is UCB.
The mechanism is quite general and could be easily extended to more
than two universes.
