This is /very/ interesting. Does it also provide such hooks for
filesystems? It would be great if we could have a way to route pathname
resolution and the 'canonical' open(), read(), write(), ioctl(), lseek(),
select(), mmap(), close() API to userspace.

I've just written a short article about what could be done with thinks
like that, see http://www.xs4all.nl/~evbergen/configuration-data.html.
I proposes the use of the filesystem to store individual configuration
items as opposed to configuration files that are 'opaque' at the OS
level, and explores userspace filesystems'es and drivers a little.

(sorry if this is off-topic and uncalled for, but I'm a little too
enthusiastic to stay quiet...)

Cheers,


Emile.
