Subject: debian: Symlink /etc/mtab
X-Git-Tag: lxc-1.1.0.alpha1~201

debian: Symlink /etc/mtab

/etc/mtab doesn’t exist after bootstrapping a debian container, and will
be created as regular file after first start.

That leads to at least two errors:
- output of `mount` is wrong and get messed up the more often you
  start/stop the container
- /dev/pts/ptmx has wrong permissions
