# Docker-in-LXC: neutralise AppArmor so Docker never tries to load a profile.
# In a confined LXC that fails ("docker-default ... while confined") for BOTH
# image builds and container runtime. Removing apparmor_parser makes Docker
# run everything unconfined — the container itself is the isolation boundary.
