[Nix-dev] Loading kernel modules in runInLinuxVM

[Shea Levy]

Hi all,

I'm trying to build a custom virtualbox image for nixops, and I want to
use runInLinuxVM to do so. Unfortunately, when I go to mount a btrfs
filesystem, I get an error about btrfs being an unknown filesystem type
and quick attempts to load the btrfs module fail. Is there a special way
to get kernel modules loaded inside runInLinuxVM?

Thanks,
Shea
