** Description changed:
+ ============================================
+ SRU Justification:
+ 1. Impact: cgroup-lite fails to start on systems with separate /usr
+ 2. Development fix: move cgroup-{,u}mount commands to /bin
+ 3. Stable fix: same as development fix
+ 4. Test case:
+ 1. install a system with separate /usr
+ 2. install cgroup-lite
+ 3. reboot, then run 'sudo status cgroup-lite' to check whether cgroup-lite
+ is stopped
+ 5. Regression potential: If done wrong, it could cause cgroup-lite to fail
+ to start or stop.
+ ============================================
+
the initscript provided by cgroup-lite 1.1 doesn't work when /usr is on
separated partition.
