Impact: users who have cgroups mounted in more than one place will hang thier + system when starting an lxc container + 2. Development fix: check for duplicate cgroup mounts + 3. Stable fix: same as development fix + 4. Test case: + sudo apt-get install lxc + sudo lxc-create -t ubuntu -n r1 + sudo mkdir /var/cgroups + for d in `sed -e '1d;s/\([^\t]\)\t.*$/\1/' /proc/cgroups`; do + sudo mkdir -p /var/cgroups/$d + sudo mount -t cgroup -o $d cgroup /var/cgroups/$d + done + sudo lxc-start -n r1 + + If the lxc-start does not hang, the bug is not present. + 5. Regression potential: + + =========== SRU Justification =========== + + + I've played around with steam-lxc, but the container fails to start.
