Description:
  Physical to container migration tool

  This tool lets you turn any Linux filesystem (including your current one)
  into a LXD container on a remote LXD host.

  It will setup a clean mount tree made of the root filesystem and any
  additional mount you list, then transfer this through LXD's migration
  API to create a new container from it.

  The same set of options as `lxc launch` are also supported.

Usage:
  lxd-p2c <target URL> <container name> <filesystem root> [<filesystem mounts>...] [flags]

Flags:
  -c, --config        Configuration key and value to set on the container
  -h, --help          Print help
  -n, --network       Network to use for the container
      --no-profiles   Create the container with no profiles applied
  -p, --profile       Profile to apply to the container
      --rsync-args    Extra arguments to pass to rsync
  -s, --storage       Storage pool to use for the container
  -t, --type          Instance type to use for the container
      --version       Print version number
