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 ]
  mv /dev/shm /dev/shm~
  mkdir /dev/shm
  mount --bind "`readlink -f /dev/shm~`" /dev/shm

Setting up Distel and erlang remote shell for membase

I decided to do myself a small present. I've just wrote some Emacs lisp code that via REST API grabs erlang otp node and cookie and connects my emacs with that node. I've made integration with Distel and erlang remote shell. The later was most problematic because of quite weird TTY handling in Erlang shell. But in the end it seems to work great! Grab code here: And the usage is M-x alk-membase-shell and M-x alk-membase-setup-distel.
