I can't say exactly. But I distincly remember that you discussed the
semantics of file deletion in unionfs on IRC with some others. Various
ideas were thrown around, problems pointed out -- it was obvious that
this is really a complex topic hard to figure out.

And it appeared to me that every implementation of unionfs must face the
very same problems. So I suggested checking how others have solved it --
surely the popular implementations in Linux etc. have spent a lot of
thought on that, and the conclusions shouldn't be any different for
us...

I hope the way I wrote this above wasn't offensive -- I see now that it
might be :-(
