Hi Andew,

Sorry for submitting a patch that got nacked. I have two other in befs, but they
are small and trivial.

That is a good point. One of the reasons I've been reading the Linux
implementation of befs is because it is unmaintained. I thought I could help, but
it also means there isn't huge interest for more support.

Do you have any suggestions of more modest projects within other file systems?
Something that would be a better time investment.

Thanks for the help,
Luis
