Bug Description

Using lxd 2.0.2-0ubuntu1~16.04.1 on Xenial.

"lxc launch ubuntu:xenial foo" works.
"lxc launch ubuntu:yakkety foo" does not work: it says "error: The requested image couldn't be found."
"lxc launch images:ubuntu/yakkety/amd64 foo" works.

"lxc launch images:debian/sid/amd64 foo" fails with":
error: Error calling 'lxd forkstart foo /var/lib/lxd/containers /var/log/lxd/foo/lxc.conf': err='exit status 1'
Try `lxc info --show-log foo` for more info

In that output I see:

            lxc 20160609115553.749 NOTICE lxc_start - start.c:start:1411 - exec'ing '/sbin/init'
            lxc 20160609115553.749 ERROR lxc_start - start.c:start:1414 - No such file or directory - failed to exec /sbin/init

If I look in /var/lib/lxd/images/<hash>.zfs, I see that rootfs/sbin/init does not exist, whereas it does for my working containers. So it seems to me that the Debian sid image as supplied by images.containers.org is broken.

I should mention that the hash of the broken image is 9e974be4294f

It's broken because a clean deboostrap of sid (unstable) doesn't seem to include a working init system at the moment.

root@dakara:/var/lib/lxd/containers/foo/rootfs# ls /sbin/init -l
lrwxrwxrwx 1 root root 20 May 12 05:39 /sbin/init -> /lib/systemd/systemd
root@dakara:/var/lib/lxd/containers/foo/rootfs# ls -lh lib/systemd/systemd
ls: cannot access 'lib/systemd/systemd': No such file or directory

As mentioned on https://images.linuxcontainers.org, those are unofficial images (not that Debian is publishing any official ones), are auto-generated and come with no guarantee whatsoever.

We do publish the past 3 images on the server though, you can get the hash of earlier builds by looking at "lxc image list images:". If the problem persists, you may want to file a bug report with Debian to fix unstable.
