lxd-launch

#!/bin/bash

# Create a privileged lxd container and bind mount current user's home
# directory into it. This script assumes that the ubuntu user inside the
# container and your current user have the same id: this is usually true in the
# typical one-user development machine. This script automates what described at
# <https://tribaal.io/mounting-home-in-lxd.html>.

# Save this script in your path, for instance as "lxc-launch-and-bind" and run
# it without arguments for usage instructions.
