But I can't distribute the file fs with my application,
because I can't expect my
user base to patch and recompile their kernel just so they can run
my application.

Perhaps what is needed is an 'inuse' filesystem or a way to make
filesystem modules without patching the kernel.

My concern is that ordinary tools like mount check the proc filesystem
to see if a partition is already mounted and it seems likely that tools
like mke2fs do this too. Sysadmins might feel that existing tools
them from damaging something in use. I'm looking for a way to follow
general behavior with raw partitions.
