I already said this before but just to repeat, since I'm confused:

How would "lklfuse" be different from http://libguestfs.org/
which we at Red Hat (and a number of other organizations)
use quite widely now for build systems, debugging etc.

In the end it's just running the kernel in KVM with a custom protocol,
with support for non-filesystem things like "install a bootloader",
and it already supports FUSE.

I'm pretty firmly with Al here - the attack surface increase here
is too great, and we'd likely turn this off if it even did make it
into the kernel.
