It'd be nice to validate the prerequisites (e.g. in `debconf` or at
start) and fail with a better feedback (either at start, through package
dependencies or a debconf warning (that the program can't be used or
needs to be reconfigured)) or change default settings at installation.

Title:
  lxc-start fails due to insufficient permission for creating netdev

Status in lxc package in Ubuntu:
  Invalid

Bug description:
  After installing an lxc with `sudo lxc-create -n Ubuntu-12.04.5-i386
  -t /usr/share/lxc/templates/lxc-ubuntu -- --release precise --mirror
  http://richtercloud.de:3142/de.archive.ubuntu.com/ubuntu --arch i386`,
  starting the container with `sudo lxc-start -n Ubuntu-12.04.5-i386
  --foreground` fails due to the following error:

      lxc-start: conf.c: instanciate_veth: 2817 failed to attach 'vethY1J1I1' to the bridge 'lxcbr0' : Operation not permitted
      lxc-start: conf.c: lxc_create_network: 3100 failed to create netdev
      lxc-start: start.c: lxc_spawn: 829 failed to create the network
      lxc-start: start.c: __lxc_start: 1087 failed to spawn 'Ubuntu-12.04.5-i386'
      lxc-start: lxc_start.c: main: 337 The container failed to start.
      lxc-start: lxc_start.c: main: 341 Additional information can be obtained by setting the --logfile and --logpriority options.

  It should be possible to start the container right away after
  installation of the apt package and handle eventually necessary setup
  tasks (of permissions, etc.) in `debconf`.

  Currently it's necessary to comment out all `lxc.network.*` entries in
  the container configuration file.
