And when is use lxc-start -n base and start the container base and then
when I add user, it is shows the entry of user in /home of container and
also in /etc/group of container.

My doubt is when i use lxc-execute and add user why it not adding the entry
in /etc/group of container and why it is adding when i use lxc-start?
