[Buildroot] Failing NFS root mount (SOLVED)

[Guillaume Dargaud <dargaud@lpsc.in2p3.fr>]

In retrospect that makes a lot of sense... (but then again, so do many 
things in life).

I was exporting with NFS the project_build_powerpc/genepy/root directory to 
mount as root. And that failed.

But then if do:
mount -o loop binaries/genepy/rootfs.powerpc.ext2 /media/loop/
And export /media/loop instead, I can boot fine !!!

Doing a diff between the two dirs reveals that for instance the devices are 
normal files in the project directory...

I saw your reply right after solving it and that confirms it...

Thanks to all who contributed.
