By default ConditionFirstBoot is ankered to the presence of
/etc/machine-id. However, in our case /etc/machine-id is a bind mount,
which makes the first boot condition non-working.
Since machine-id is stored by the bootloader on HAOS, use the boot
loaders knowledge and pass the information to systemd.
The new systemd version v252 brings a new naming scheme, in particular
it seems that on device tree based systems (e.g. Raspberry Pis) the
Ethernet device name changes from eth0 to end0.
This breaks a previously made configuration.
Even worse, it seems that the default NetworkManager behavior is to only
configure a network device if there is no profile. But since profiles
are configured on a typical installation, NetworkManager doesn't bring
up any of the network interface, leaving the user stranded on an
unconnected system.
Ideally, we should have a plan how to migrate from one naming scheme to
the next. For now, just stick with the naming scheme HAOS 9.x has been
using.
* Add squashfs with LZ4 and LZO compression to Barebox
* Add squashfs with LZO compression to U-Boot
* Use squashfs for Linux kernel partition
Generate a squashfs image with LZO compression for the Linux kernel
partition. Adjust the boot scripts to be file system independent commands
to boot from squashfs.
The change "Avoid trying to boot non-existing kernel image in failover
case" introduced a broken boot script on Raspberry Pi (when booting from
partition B) and ODROID-XU4.
* Avoid trying to boot non-existing kernel image in fail-over case
The A/B update system automatically switches to the other boot slot when
booting fails. However, in a fresh installation, only boot slot A
exists. If booting fails three times (e.g. if somebody plugs out power
before the slot can be marked as good), then the system switches to boot
slot B which does not contain a kernel image yet. Avoid trying to boot
the non-existing kernel image.
With this change, if slot B is empty U-Boot will restore both slots to 3
attempts and retry booting from slot A on next reboot:
```
Trying to boot slot B, 2 attempts remaining. Loading kernel ...
** Unrecognized filesystem type **
No valid slot found, resetting tries to 3
storing env...
```
