When starting an initrd the kernel expects to find /dev/console in the initrd,
so that it can connect it as stdin/stdout/stderr to the /init process. If the
device node is missing the kernel will complain that it was unable to open an
initial console. If kata-agent is the initrd init process, it will also result
in log messages not being logged to console and thus not forwarded to host
syslog.
Add a set of standard device nodes for completeness, so that console logging
works. To do that we install the makedev packge which provides a MAKEDEV helper
that knows the major/minor numbers. Unfortunately the debian package tries to
create devnodes from postinst, which can be suppressed if systemd-detect-virt
is present. That's why we create a small dummy script that matches what
systemd-detect-virt would output (anything is enough to suppress mknod).

Instead of removing the non-needed packages under `/usr/share` and then
installing new components, let's make sure we do the removal at the end
of our script.

Let's do that instead of updating and installing the
`software-properties-common` package, as it reduces the final size of

First of all, EAA KBC is only used with TDX, thus we can safely assume
that eaa_kbc means TDX, at least for now.
A `/etc/tdx-attest.conf` file, with the data "port=4050" is needed as
that's the default configuration for the Quote Generation Service (QGS)
which is present on the guest side.

Inclavare released a rats-tls-tdx package, which we depend on for using
verdictd.
Let's install it when using EAA_KBC, as already done for the rats-tls
package.
One thin to note here is that rats-tls-tdx depends on libtdx-attest,
which depends on libprotobuf-c1, thus we had to add the intel-sgx repo
together with enabling the universe channel.

We're currently using Ubuntu 20.04 as the base for the Ubuntu rootfs,
meaning that right now there's no issue with the approach currently
taken. However, if we do a bump of an Ubuntu version, we could face
issues as the rats-tls package is only provided for Ubuntu 20.04.

1. Implemented a rust module for operating cgroups through systemd with the help of zbus (src/agent/rustjail/src/cgroups/systemd).
2. Add support for optional cgroup configuration through fs and systemd at agent (src/agent/rustjail/src/container.rs).
3. Described the usage and supported properties of the agent systemd cgroup (docs/design/agent-systemd-cgroup.md).

Use `multistrap` for building Ubuntu rootfs. Adds support for building
for foreign architectures using the `ARCH` environment variable
(including umoci).
In the process, the Ubuntu rootfs workflow is vastly simplified.

- no need to create `/usr/lib/systemd/systemd` link any more
- install `chrony` as extra package and install extra packages in chroot
rather than `debootstrap`, because `chrony` provides `time-daemon`,
which under 20.04 is provided by `systemd-timesyncd`, which is
required by `systemd`, and `debootstrap`'s conflict resolvement can't
handle this, but `apt`'s can.
