It seems to be useful for things like FS encrytion and compression...
is there any plan to implement something similar in Solaris??
If you google "stacking file system" you'll find a lot of information
and papers dating back to the late 1980s - early 1990s. Encryption and
compression are (IMHO) the most often cited "reason why this is a great idea
and I can't believe nobody has thought of it before."
Perhaps the most interesting is response is from Apple,

So, while it might be cool, the idea hasn't seemed to evolve much from 1990.
