[lxc-users] sysctl -p no longer allowed in container

My scripts were (unwisely) expecting to be able to do things like
echo "kernel.sem = 250 65536 32 32768" | sudo tee -a /etc/sysctl.conf
sudo /sbin/sysctl -p
inside the container. Tsk. I seem to have gotten away with it in
Ubuntu 12.04, but Ubuntu 14.04 complains
+ sudo /sbin/sysctl -p
sysctl: permission denied on key 'kernel.sem'
That makes sense -- containers shouldn't be able to tweak kernel parameters.
So now I'm rejiggering my scripts to do that outside the container.
