From what I see LXC/LXD is great for checking out different Linux distro’s.
But to get a good grip on how it is to use the distro in day-to-day work, you usually need to run as the normal (non-root) user.
To get the nonprivileged user console in a container spawned from the official Ubuntu image, I do:
$ lxc launch ubuntu: some-ubuntu $ lxc exec some-ubuntu -- /bin/bash $ su ubuntu
Is there some other, more elegant way of doing that?
