[lxc-users] LXD an "hypervisor" for containers (based on liblxc)

[Ranjib Dey]

this is awesome. how can we contribute to this project :-) . I am already
using LXC and building & deploying the rootfs via CI (go-cd+ chef). having
lxd in place will make all those integration lot more thin and clear.

thanks for doing this :-)
