Fixes to almost-ensure there is a working serial console 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.

Description=Reconfigure raspi-firmware to regenerate config.txt matching actual hardware
rootfs: Eliminate circular dependency between systemd units 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). Resolves: image-specs#45 Resolves: image-specs#49 Signed-off-by: Simon McVittie <smcv@debian.org>
