fakemachine launches a virtual machine reusing the host system's /usr,
and runs commands as root on that virtual machine. It's used by debos,
but can also be used to wrap arbitrary commands, in particular vmdb2;
it's enough to run the parts of vmdb2 that need to mount filesystems
and run apt.
This won't work if fakemachine isn't available (in particular on non-x86),
but that seems better than just failing altogether.

This is needed to use Debian repos served over https, but also a LOT of
other programs, like reportbug, which want to communicate securely.
Also sorted the list of packages alphabatically as I couldn't find a
reason for the current order and then a logical sort order is better.

Switch away from using a systemd service for the initial root resize.
Instead, we resize the root partition and filesystem in the initrd.
To simplify things, the initrd script will check whether it should resize
the partition on every boot. It does this by checking if the entire disk
(ignoring an empty 4MB) is in use. However, the scripts themselves are
deleted from the system after the initrd is generated. After the image
is installed, the resize script should exist only in the initrd. When the
kernel gets upgraded (eg, for a security update) or a new initrd is generated
due to a package install, the new initrd will not contain the resize script.
At that point, nothing will remain from the image's initial resize
bootstrapping process.
This process (but not the scripts) is similar to what cloud-initramfs-growroot
does. However, that particular package has an indirect dependency on Python,
and we don't necessarily want that overhead in our images just for resizing.
bmaptool(1), from the bmap-tools package, can write the used blocks
in a sparse disk image to media, while saving time and I/O by not writing
zeroes to the unused blocks. Typical use:
make raspi2_bullseye.img.bmap raspi2_bullseye.img.xz
... upload those two files ...
... download those two files ...
bmaptool copy raspi2_bullseye.img.xz /dev/disk/by-id/usb-Generic-_SD_MMC_*-0:0

rpi-reconfigure-raspi-firmware.service requires /boot/firmware to be
mounted, but mounting local filesystems requires local-fs-pre.target,
so trying to run rpi-reconfigure-raspi-firmware.service before
local-fs-pre.target results in a cyclic order dependency. systemd
breaks the cycle in an arbitrary place, and the result is unlikely to be
what we want.
Instead, delay reconfiguration of config.txt until after local
filesystems are mounted, but before sysinit.target. This breaks the cycle
(image-specs#49).
This still orders it before all non-early-boot services, because
sysinit.target is part of the DefaultDependencies; so in particular
it will finish before rpi-generate-ssh-host-keys.service starts, which
avoids the two services fighting over the dpkg lock (image-specs#45).

Distributing vc4-blacklisted images is a disservice to our users as soon as
vc4+serial work again, and RPi4 is quite often used for desktop or multimedia
tasks.
It now xz compresses the image and then still calculates the sha256 hash
on the non-compressed file. The xz.sha256 target (already) compresses it
and calculates the hash on the xz file.

Why almost? Because Rpi0w uses ttyS1 instead of ttyAMA0 desipte being part of the RPi1 family...
...But it will work fine for the _second_ boot onwards, if things go according to plan.
For all other RPi models, it should work from the first boot on.
