With LXC, you can override the value of an environment variable to
null, but you can't unset an existing variable.

The NVIDIA hook was previously activated when NVIDIA_VISIBLE_DEVICES
was set to null. As a result, it was not possible to disable the hook
by overriding the environment variable in the configuration.

The hook can now be disabled by setting NVIDIA_VISIBLE_DEVICES to
null or to the new special value "void".

debian: Use iproute2 instead of iproute

The package has pretty much always been iproute2 with iproute being an
alias for it, the alias is now gone so we need to use iproute2.

Unpriv fixups

Signed-off-by: Tycho Andersen <tycho@tycho.ws>

In particular, if we are already in a user namespace we are unprivileged,
and doing things like moving the physical nics back to the host netns won't
work. Let's do the same thing LXD does if euid == 0: inspect
/proc/self/uid_map and see what that says.
Signed-off-by: Tycho Andersen <tycho@tycho.ws>

Consider the case where we're running in a user namespace but in the host's
mount ns with the host's filesystem (something like
lxc-usernsexec ... lxc-execute ...), in this case, we'll be euid 0, but we
can't actually write to /run. Let's improve this locking check to make sure
we can actually write to /run before we decide to actually use it as our
locking dir.

[cgfsng] show wrong errno

lxc_cgroup_set_data: h = get_hierarchy(controller);
if h is NULL, now errno is old, it donot set new one.
And then,
cgfsng_setup_limits:

    if (lxc_cgroup_set_data(cg->subsystem, cg->value, d)) {
		if (do_devices && (errno == EACCES ||
			errno == EPERM)) {
			WARN("Error setting %s to %s for %s",
				cg->subsystem, cg->value,
				d->name);
			continue;
		}
		SYSERROR("Error setting %s to %s for
			 %s",
			 cg->subsystem, cg->value,
			 d->name);
		goto out;
	}

SYSERROR will show old errno, make me confused.

Since we write the label directly without going through the AppArmor API it
doesn't make sense to link against it.

We can simply write the label ourselves. There's no magic happening.
