I would do that differently for Haiku. With the last bigger FS interface
change I introduced support for FS layers. Since no layer has been
implemented yet, the interface has not really been tested and might need
some tweaking, but anyway... The two most interesting FS layers would be (1)
a layer that adds attribute support to a FS that doesn't support attributes
and (2) a layer that adds write support to a read-only FS (by storing the
changes in RAM). (1) would allow booting from filesystems other than BFS,
most interestingly from ISO CDs (as opposed to CDs with an ISO track and a
BFS track). (2) would additionally provide the "live" part.
