Because it's needed for things like the Android container on Ubuntu
Touch, application containers on OpenWRT, ...

There are legitimate use cases for those features, those use cases just
never apply when running a full Linux distro inside the container :)

LXC used to default to sharing the netns by default when no lxc.network
entry was set, that was clearly bad design and we've fixed that (no
defaulting to an empty netns), but if someone specifically sets
lxc.network.type=none or passes --share-net 1, we give them exactly what
they requested.

Title:
  lxc-stop powered off a server

Status in lxc package in Ubuntu:
  Incomplete

Bug description:
  Hi,

  Earlier today, a server got powered off and I'm 99% sure it's because I ran the following command as root :
  # lxc-stop -n <container>

  The container was started manually with :
  # lxc-start -n <container> -F --share-net 1

  and it wasn't fully booted (ie I didn't have the console yet).

  syslog just showed :

  and that's it. I don't have other relevant logs to offer I'm afraid.
