Moving individual files between filesystems should be extremely
portable; I'm pretty sure V6 could do this. Not atomic, though,
which bit us recently (when doing "mv newfile existingfile",
there's a critical section where neither the old nor the new
version of existingfile actually exists -- not nice if the file
in question is your (semi-dynamic) home page...)
I very much doubt that V6 could handle directories, though. I'm
not sure how portable this is, but I'd be willing to bet its
portability closely correlates with that of "cp -r" :-)

Nobody ever got fired for buying Microsoft -- but they could get
fired for relying on Microsoft.
