Unbreaking LXC on latest Debian unstable

With recent switch to /run directory in Debian I was getting error from lxc when it was trying to mount /dev/shm in container and failed because /dev/shm is now symlink to inside /run. The simplest fix I found is replacing symlink with bind mount. Here's what I've added to /etc/rc.local

if [ -L /dev/shm ]

then

  mv /dev/shm /dev/shm~

  mkdir /dev/shm

  mount --bind "`readlink -f /dev/shm~`" /dev/shm

fi
