Public bug reported:
=================================
SRU Justification
1. Impact: cgmanager takes 8 seconds or more for each reply
2. Fix: an upstream patch which mounts a tmpfs onto /root is backported
3. Regression potential: there should be none
4. Test case:
stop cgmanager
mount --bind /root /root
mount -o bind,remount,ro /root
start cgmanager
cgm ping <- this will be slow
=================================
Cgmanager links against dbus which attempts to open /root/.dbus-
keyrings/org_freedesktop_general.lock. We don't actually need that, and
/root is sometimes ro (especially at early boot).
