Well if you restrict yourself to the LispOS world, then nothing on the
Unix side of things should break. They only break when you do things
the Unix way.

I havn't used NeXTstep, but I heard that while they use a UNIX file
system it is completely hidden by the NeXT object paradigm.

In a similar way, Linux has a feature to make a brain-dead MS-DOS file
system have all the extra things of a Unix file system (like symbolic

In the same way you can build a lisp file system on top of the Unix
file system and save some work in the short run, while still providing
all the above features that you so desire.
