Hi Emery,

thank you for considering my suggestion!

I think that besides enabling package management on Genode, bringing the
Nix package manager to Noux would have a very welcome side effect with
respect to the overall theme outlined in my initial posting (making
Genode usable). I expect that you will hit several limitations of Noux
(e.g., functional gaps or performance issues) on your way. So stressing
Noux by your line of work would pressure us to fix those issues and make
Noux better for everyone. In this spirit, I encourage you to share any
trouble of using Noux with us. ;-)

I agree. From reading the Nix documentation, I even got the impression
that some of the "quirky" aspects of Nix (i.e., the need of the Nix
daemon) stem from Linux' limitation of having one global VFS. On Genode,
we don't have this limitation as each Noux instance can have its own
VFS. I am curios to see how this may benefit the use of Nix on our platform.
