I'm reading my emails frequently, eagerly awaiting a reply to this bug report!
Note, I am going to move up to the 2.6.25.6 kernel for Puppy Linux, and if you Unionfs developer guys can figure out why I'm getting crashing, I'll apply the fixed patch -- well, I can't use 2.3.3 as-is, so have to wait until you can come up with something.
