Where union mounts is right now is in need of more review from VFS experts (and thanks to those who have already reviewed it). I'm rewriting the in-file copyup code right now, which is dependent on a lot of ongoing VFS work by Al Viro, Nick Piggin, Dmitriy Monakhov, and others. Here's my description of the problem I'm currently working, which is where I could use review the most: http://groups.google.com/group/linux.kernel/msg/217ca5aedbd7bfd0 Like anyone else, VFS developers prioritize what they are working on, and unioning file systems in general tend to be low on the list. Union mounts is my first priority but not anyone else's. :) Thanks for your email, -VAL
