Hi,

I am sorry but this is not something to be done by LXC: LXC is an end
user program that should not load any third party driver automatically.

It's the job of the system administrator to add to modules-load.d the
configuration to load such modules on their machines.

With best regards,

It's far easier to fight for principles than to live up to them.
