To add the custom overlay,
$ git clone https://github.com/lramage94/dotfiles ~/.dotfiles $ cat << EOF > /etc/portage/repos.conf/dotfiles.conf > [dotfiles] > location = /usr/local/portage/dotfiles > sync-type = rsync > sync-uri = file:///home/lramage/.dotfiles/.local/usr/local/portage/dotfiles > priority = 9999 > EOF
emerge --sync dotfiles to sync the overlay.
To create the container,
# First it needs to be unmasked. $ echo "lxc-container/paho-mqtt ~amd64" > /etc/portage/package.keywords/paho-mqtt $ emerge lxc-container/paho-mqtt
