Linus,
the HFS guys made a point of making the filesystem capable of being tar-copied. I think that this is a useful feature. It's not that we can't change tar: We have the source. It's that lots of Unix programs make assumptions (similar to what tar does) about what a directory tree looks like. Now you've never wanted to use tar to copy a /procfs. But it works on NFS.
So, (I must've missed the first part of this discussion) what's wrong with the HFS way of doing things?
~/myfile (data fork) ~/.resource/myfile (resource fork)
This may not be "generic" enough for abitrarily named forks. Think of something that IS. It's not all that hard:
~/myfile (data/default fork) ~/.streams/myfile/resource (resource fork) ~/.streams/myfile/Icon (icon fork) ~/.streams/myfile/default (hardlink to ~/myfile )
Advantages:
- Tar-copyable. - Unix utilities don't see anything odd. - ls will show you just the "files" (unless -a or -R).
Disadvantages:
- The resource fork is a bit "far" away from the data fork. (myfile/data and myfile/resource are indeed closer)
Anything I've missed?
Roger.
