[Bug 1045955] Re: lxc-create -t ubuntu-cloud broken on quantal images (no ubuntu user)

[Stéphane Graber]

** Changed in: lxc (Ubuntu Precise)
       Status: Triaged => In Progress

** Changed in: lxc (Ubuntu Precise)
     Assignee: (unassigned) => Stéphane Graber (stgraber)

** Description changed:

+ === Rationale ===
+ The quantal cloud image doesn't ship with an existing ubuntu user, instead it uses cloud-utils to create it at boot time.
+ This breaks older versions of lxc-ubuntucloud which expects the user to be there.
+ 
+ The fix is a backport from what was pushed into quantal and basically
+ moves the user handling code to the cloud-init config file.
+ 
+ === Test case ===
+ 1) lxc-create -t ubuntucloud -n p1 -- -r q
+ 2) If this works, you're good (otherwise it'll fail when setting up the user saying that "ubuntu" doesn't exist.)
+ 
+ === Regression potential ===
+ The fix is a direct port of the change that was pushed to quantal and it's been tested on 12.04 with both a precise and quantal container. In the worst case, cloud-init would fail to run, rendering the container close to useless, but the testing I've been doing would have shown anything that bad.

+ ------ original bug report --------
+ 
  'lxc-create -t ubuntu-cloud' was broken on quantal images as it assumes
  presense of 'ubuntu' user, and that has been removed from the images.
  Now, cloud-init creates the ubuntu user on first  boot.
