Public bug reported:

Libvirt's LXC implementation exposes a read-only `/proc/sys/net` to
guests.

This can cause guest's default network configuration scripts to fail
when trying to bring up `IPv6` interfaces.

The short-term fix is to use `postup-hooks` to configure the interface.

Longer-term, we may want to consider a writable `/proc/sys/net` (we just
need to verify that this can be done securely).
