[lxc-users] upgrading to lxd-daily and migrating to unprivileged containers

[Stéphane Graber]

Right,

The lxc-* commands are to control LXC itself. They are in no way
deprecated and we still expect a lot of people to use them.

LXD is a new take on the whole container experience. It still uses LXC
behind the scene through liblxc, however the lxc-* commands will not let
you interact with LXD containers (at least not easily). Instead we have
that unique "lxc" command which interacts with local or remote LXD
daemons.

So yes, "lxc-attach -n first" is now "lxc exec first /bin/bash" and all
interactions with that container should be done with sub-commands of
"lxc".
