** Description changed:
+ ==============================
+ 1. Impact: cloud image creations can fail. This causes juju with local
provider to fail.
+ 2. Development fix: use --numeric-owner when un-tarring ubuntu images, to
make sure that /home/ubuntu in the container is owned by the right ubuntu
userid.
+ 3. Stable fix: same as the development fix
+ 4. Test case:
+ 1. add an ubuntu user if one does not yet exist on the host - make sure
it is not uid 1000
+ 2. lxc-create -t ubuntu-cloud -n c1
+ 3. check /home/ubuntu in the container - it will be owned by the ubuntu
userid on the host.
+ Additionally, when starting c1, you will be unable to log in as user
ubuntu.
+ 5. Regression potential: this should introduce no regressions, as it only
makes sure that the owners of files in the container match the username-userid
mapping in the container's password file.
+ ==============================
+
Permissions on the created lxc container somehow are reflecting the
users /etc/password file:
ubuntu@dpb-local-landscape-client-0:~$ cat /etc/passwd |grep landscape
landscape:x:104:109::/var/lib/landscape:/bin/false
ubuntu@dpb-local-landscape-client-0:~$ ll /etc/landscape
total 12
drwxr-xr-x 2 root root 4096 Oct 12 17:48 ./
drwxr-xr-x 86 root root 4096 Oct 12 17:47 ../
-rw------- 1 999 root 164 Oct 12 17:48 client.conf
ubuntu@dpb-local-landscape-client-0:~$ logout
Connection to 10.0.3.143 closed.
dpb@starbuck:dpb-local$ cat /etc/passwd |grep landscape
landscape:x:999:999::/var/lib/landscape:/bin/false
dpb@starbuck:dpb-local$
My hunch is where the tar happens from the mount of the downloaded image
in lxc/templates/lxc-ubuntu-cloud
