I do not know.

Just wanted to comment a bit on the question. wrapfs is meant to help developers writing other filesystems. It is opensource.

Developing a filesystem or device driver is not a trivial exercise. So. By asking this question the way you did, you raise another question - are you attempting to do something you may not be ready to tackle? Not that you should not try, because you will learn a lot. It is more because people will pick something to work on that is foreign enough to their skill set that it kills their desire to continue programming or working with computers.

I would suggest that, if you have not done so already, consider some reading.
This book is central to programming UNIX/Linux:
Rago and Stevens 'Advanced Programming in the UNIX Environment'

The Linux-only version of Rago: Michael Kerrisk 'The Linux Programming Interface'

Next step: Steve Pate 'UNIX Filesystems' This has a large section on Linux filesystems and user/kernel structures

Do not give up and have fun.

local-filesystems(7)					 Miscellaneous Information Manual				      local-filesystems(7)

NAME

       local-filesystems - event signalling that local filesystems have been mounted

SYNOPSIS

       local-filesystems [ENV]...

DESCRIPTION

       The  local-filesystems  event  is generated by the mountall(8) daemon after it has mounted all local filesystems listed in fstab(5).  moun-
       tall(8) emits this event as an informational signal, services and tasks started or stopped by this event will do so in parallel with  other
       activity.

       This event is typically used by services that must be started in order for remote filesystems, if any, to be activated.	Remember that some
       users may not consider it wrong to place /usr on a remote filesystem.  For most normal services the filesystem(7) event is sufficient.

       This event will never occur before the virtual-filesystems(7) event.

EXAMPLE

       A service that wishes to be running once local filesystems are mounted might use:

	      start on local-filesystems
