- This seems to be a very pointless thread.

- Why not contact the GNU people and suggest another option whic, instead of
- opening a file with fopen() or open() (whichever it uses), opens with:
-
- popen("compress -f < file");
-
- or some such. If you really want the whole thing compresses (gives better
- compression overall), then a script around a `tar -Z' type thing should be
- able to handle multi-volumes.

- Someone mentioned that a mistake early on would corrupt everything else, but
- this would be the same for a kernel level system. It shouldn't take much to
- do integrity checking of such a backup.
-
- This kind of thing has no right to be any where near the kernel.
