This was fixed upstream and included in our stable branch. A cherry-pick
was uploaded to Zesty and all tests were run successfully against it.
I have now uploaded the same thing for xenial and yakkety, they are in
the queue waiting for a SRU team member to approve them.
Once the Xenial SRU is through, I'll update the trusty-backports pocket
with it.
** Changed in: lxc (Ubuntu Yakkety)
Status: Triaged => In Progress
** Changed in: lxc (Ubuntu Xenial)
Status: Triaged => In Progress
** Description changed:
- As in topic. Since the 20161217 rootfs, after upgrade of lxc from
- 2.0.5-0ubuntu1~ubuntu16.04.3 to 2.0.6-0ubuntu1~ubuntu16.04.1 the lxc-
- android-config service does not start - making the devices unbootable.
+ # SRU
+ ## Rationale
+ LXC 2.0.6 introduced a writability test for /var/lib/lxc which breaks the
corner case of partly-writable systems like the Ubuntu phone.
+ This upload fixes this by changing the test to a simple readability one.
+
+ ## Test case
+ 1) Attempt to run lxc-start with /var/lib/lxc on a read-only filesystem but
/var/lib/lxc/<container> on a writable one.
+ 2) Confirm that the container now starts.
+
+ ## Regression potential
+ This upload only changes the check from read/write to read so the only
consequence of this should be more cases now being allowed. In the case where a
writable /var/lib/lxc is in fact absolutely required for the requested
operation, the operation will still fail, just a bit later and with a slightly
less clear error message (as was the case pre-2.0.6).

+ # Original report
+ As in topic. Since the 20161217 rootfs, after upgrade of lxc from
2.0.5-0ubuntu1~ubuntu16.04.3 to 2.0.6-0ubuntu1~ubuntu16.04.1 the
lxc-android-config service does not start - making the devices unbootable.
The syslog only states this:

This makes all of our frieza and cooler devices useless for testing
purposes.
