- The difference is it won't stick directory entries in the archive.

- Hmm, you can't use the SVR4 version of tar on the 3.2 machine, because the
- binary won't fire off, you can however use the 3.2 version on the V.4
- machine (i.e. backwords, not forward compatibility). 3.2 generated archives
- are understood by the SVR4 tar. I don't know how rfs impacts the behavior,
- I can only wonder why you would use that instead of nfs :) Seriously, we'll
- take a look, it's conceivable that the rfs code doesn't handle the truncation
- right for big inode numbers or something similar.
