This means more users will see console output at boot time.
Remove page poison from example CLIs, we should document this
elsewhere and put in blueprints.

These are not needed, but we are inconsistent. Been waiting for a
quiet moment to fix this since I noticed while doing a presentation...

These test specific combinations of TCP/UDP/IPv4/IPv6/veth/loopback
for all the kernels.
Tests take quite a while to run so there are two new labels:
'kernel' and 'kernel-extra'. 'kernel' runs the more important
tests for the two kernels we care most about. 'kernel-extra'
are additional tests for completeness.

- iproute2 provides a more complete suite of 'ip' utilities than
the busybox implementation. Useful, for debugging.
- iperf3 for network testing
- tcpdump for network debugging
- expect is used in some tests. Adding it to the base image should
make it easier to create a LinuxKit image to self-host CI.
The new version of the base package is:
linuxkit/alpine:3d57ded3edd54e616210cf0c17e3bc15eed9d03a

Formatting was incorrect due to mismatched mark; also, it appears that
qemu also uses the state directory now for the created disk image. Also
used the same italicized style for param reference in text instead of
some bracketed and some italicized.

Added a new patch to the 4.11 and 4.9 kernels based on a patch
submitted to stable: https://patchwork.kernel.org/patch/9829039/
This patch fixes a off-by-one error in the VMBus code.

Use os.Mkdirall() instead of os.Mkdir() as it does not
error if the path already exists.
This enables specifying a default config file with the image
and then over writing it with metadata.
While at it, also update to the latest alpine base image.

Current implementation hardcodes the virtual machine as
"q35" for x86, this patch remove this hardcode and config
the machine type according to the arch the VM is running.
Also, in order to make sure the qemu can run on arm64 platform,
we need to specify the vcpu type in the command line.

Some hypervisors (e.g. hyperkit / xhyve) don't provide a good way to keep
the VM's clock in sync with the Host's clock. NTP will usually keep the
clocks together, but after a the host or VM is suspended and resumed the
clocks can be suddenly too far apart for NTP to work properly.
This simple daemon listens on an AF_VSOCK port and resynchronises the VM
clock from the virtualised hardware clock.
This is a Go conversion of original C code written by

For DIRTY and RELEASED this means simply performing a static assignment with
`:=`. For HASH it is a little more complex since it is (and we want/need it to
be) a conditional assigment. However it is only used for defining TAG, so make
that a static assignment.
This reduces the number of times the complex DIRTY shell command in particular
is evaluated.

Firstly add option to disable content trust, for the use of e.g. projects which
are pushing to the linuxkitprojects org (which has no trust setup) rather than
the main linuxkit org.
Secondly, when trust _is_ enabled then enable it globally, in particular it is
now active for the `docker build` and hence containers referenced in
Dockerfiles via "FROM" will be checked.

Adds a new service for running `/sbin/acpid` that comes with busybox.
The VM will shut down if the power button is pressed.
