enabling vfs plugins with libc

Hello Genodians

I'm working on enabling vfs plugins that use libc, specifically a ported 
library. The library accesses a hardware device through a file in vfs, 
so there is no using a minimal libc implementation as it's the libc's 
vfs access that creates the chicken and egg problem preventing vfs 
plugins with libc.

The best solution I could think of this far is a special vfs server 
component that uses two vfs, one the hosts the libc using plugins and 
another that provides the vfs libc needs.

I've created a small code sample to demonstrate:

What do you think about this problem/solution?

Freundliche Grüsse
