Direct modification of branches is similar to direct modification of block devices underneith a mounted filesystem. While I agree that such a thing _should_ not oops the kernel, I'd bet that you can easily run a stresstest on a filesystem while randomly flipping bits in the block device and get just that. There are bigger problems in unionfs to worry about. Jörn -- Simplicity is prerequisite for reliability. -- Edsger W.
