Title:
[Regression] Unprivileged containers fail to start in linux-lts-utopic
Status in linux-lts-utopic package in Ubuntu:
Fix Released
Bug description:
== SRU Justification ==
Impact: linux-lts-utopic 3.16.0-46.62 contains a regression which
prevents unprivileged containers from starting due to a failure
mounting sysfs.
Fix: Backport of upstream commit
f9bb48825a6b5d02f4cabcc78967c75db903dcdc, which is marked for stable
but is missing from 3.16 stable. Another stable commit that did get
into 3.16 requires this patch.
Regression potential: This patch is specifically targeted at
unprivileged mounts of virtual filesystems in containers and fixes a
regression there. It should have no impact on mounts in the host.

linux-lts-utopic 3.16.0-46.62 contains a regression mounting
unprivileged containers. The log shows a failure mounting sysfs:
lxc-start 20150427012246.807 ERROR lxc_conf -
conf.c:lxc_mount_auto_mounts:819 - Operation not permitted - error
mounting sysfs on /usr/lib/x86_64-linux-gnu/lxc/sys flags 14
This is due to missing upstream commit
f9bb48825a6b5d02f4cabcc78967c75db903dcdc.
