Initial analysis of system default users gives that there is no real
need for a default 'factory' user to trigger a factory reset. On an
actual physical device we will have a reset button or a menu option in
the bootloader to trigger factory reset, and in both physical and
virtual (GNS3) devices a logged in admin user can call the factory
command.
A virtual device that cannot be logged in to will have to be removed and
have its persistent backing store deleted, but that is the only real
downside to removing this user. The idea is to set a kernel command
line flag from the bootloader, and that could also be done from, e.g.,
GNS3.

The /var, and particularly /var/lib, directories are used for persistent
storage for various system daemons. While adding support for containers
it became clear we had to change how we make these directories writable.
Both LXC and Podman use OverlayFS for the writable layer, and you cannot
set up an overlay on top of another overlay.

Podman (POD manager) is an open source tool for developing, managing,
and running containers on your Linux systems.

A generic replacement for src/net with some advantages:
- Shell script is well-suited to these kinds of tasks, making this
implementation much simpler.
- Allow arbitrary number of actions (not just init/exit), this can be
used to implement things like `dagger exec up/down`.
- Allow arbitrary number of scripts for each action/node tuple. This
will let us handle more complex scenarios in confd without having to
fiddle about with src/net.
This allows you to define a single "logical" config that can be
tailored to the specific system based on the available interfaces,
base MAC address etc.
This commit enables support for running custom startup scripts at boot,
allowing a mix of a NETCONF-based system and Classic /etc. For example,
use NETCONF to set up network interfaces, users, etc. and runparts for
enabling and configuring the device as an OSPF router.

With the introduction of the -classic defconfigs we need to also make
sure to name the resulting artifacts accordingly:
- infix-$ARCH.{gns3a,img,pkg}
- infix-$ARCH-classic.{gns3a,img,pkg}
For release builds the version (-23.02-$REV) will be appended before
the file suffix, e.g., infix-x86-64-classic-23.02-3.img

- board/common: drop everything not needed by NETCONF mode
- board/classic: most board/common helpers relocated here
- Simplify Finit scripts for critical services
- Source variant from /etc/os-release to select ramdisk /etc

A long standing internal debate comes to its logical conclusion. Arch
naming should follow GCC. The "native /etc" has also found a better
name: classic!
README and GitHub action has been updated accordingly.

- Drop unused packages in NETCONF (default) mode
In the default build we will use the net tool instead of iupdown-ng,
p-net & Profeth will move to customer-specifc builds with another
licensing model.
- Split out NETCONF specific parts from board/common to board/netconf

This build is intended as a base reference and for use as a very simple
end device. The default starts DHCP and IPv4LL (ZeroConf) on eth0, but
can be configured by editing /etc/network/interfaces.d/*

With the new templating support in Finit, and this patch, we can now
very easily enable a ZeroConf service on, e.g., eth0:
$ initctl enable zeroconf@eth0

This means that:
- The full boot order is now respected, using the magic "fallback"
varible in GRUB. This means that if an entry fails to load, we move
on to the next one in the defined order.
- Netbooting is supported. In this mode, GRUB will acquire an IP
address using DHCP, after which it downloads an image using TFTP.
- If we run out of valid entries, we always make sure to reboot. This
ensures that, e.g., a temporary TFTP server outage does not cause an
Infix device to get stuck in GRUB.
At the moment, the image handling is excruciatingly inefficient when
netbooting, as the image is downloaded multiple times behind the
scenes. Ideally, downloads would be cached, but a quick investigation
indicates that an implementation of this would take more time than we
can spare at the moment. Therefore, we settle for the working, though
wasteful, implementation.
The per-interface and per-af setting in the ietf-ip yang module allow
the user to enable a more granular forwarding between interfaces, which
is disabled by default.

Instead of having to rely on the kernel command line, we convert all the
kernel functionality in question into modules and rely on the auto-load
feature in the kernel and modprobe to add options at load time.
The fb_tunnels setting is a net core setting, for that we use sysctl.
This commit also syncs the kernel config between our two main archs,
disabling DRM and SOUND for the Amd64 build as a spin-off.

This commit adds multi-nameserver support using openresolv (resolvconf)
and dnsmasq. This means that a DHCP client (dhcpcd) or VPN client can
be providers of nameservers to the system. Dnsmasq takes over as the
system resolver, except when the user has set up static configuration.
Static nameserver(s), as well as search and options, are always added
first by openresolv to /etc/resolv.conf.

In managed NETCONF mode /etc is always based on the image's read-only
/etc with a read-writable overlay as a RAM disk. We control the image
and know the default rc.local is empty and the interfaces file only
list the loopback interface.
