* Add tempio host package
tempio is a template helper using Go's template engine and sprig
functions.
* Use tempio to generate rauc manifest
* Use tempio to generate rauc system.conf
* Drop unnecessary device tree utilities
They have been used for Barebox which uses device tree to configure the
state storage and its location. With the change to GRUB the tools are no
longer required.
* Determine manual GRUB update depending on installed tools
Manually update the GRUB environment if no grub environment tools are
installed. This makes a upgrade work even after a previous downgrade (in
that case a grubenv file might still be present in the UEFI ESP).
* Use shell functions for install hooks
* Use post-install hook to initialize GRUB2 bootloader env
Unfortunately the boot name to be updated (RAUC_SLOT_BOOTNAME) is not
available when updating the "boot" slot. Instead, initialize the boot
slot in a kernel post-install slot.
* Fix migration from Barebox GRUB
Create GRUB env which defaults to the boot slot we are updating to. This
makes sure that the newly installed OS version will be booted on next
reboot even if installed on boot slot B.
* ODROID XU4: Update U-Boot on eMMC boot partition
Update the U-Boot on the eMMC boot partition if present. Only write the
first megabyte as the eMMC boot partition might be smaller than the SPL
image and only the first megabyte is occupied by FW/BL1/BL2/TZSW (see
https://wiki.odroid.com/odroid-xu4/software/partition_table#tab__odroid-xu341).
* Check if Busybox supports oflag
It seems that Busybox' dd shipped with OS release 5 and earlier does not
support oflag. Check if the flag is supported before making use of it.
* Exit if a command in the update scripts returns an error
This makes sure that the update isn't marked as successful in case there
is an error in the update script.
The rauc hook for the spl slotclass writes to the disk directly. Make
sure the changes do not end up in cache in case the device looses power
or is otherwise not properly rebooted.
Also use the same partition label detection we are using in
hassos-expand.
* Fix issue with latest shellcheck version
The latest shellcheck versions use a new error number for non-POSIX
string replacement. Change to ignore this new error number.
* Ignore shellcheck issue about not following sourced files
Newer shellcheck versions also warn when shellcheck does not follow
sourcing of files with known path:
Not following: ./meta was not specified as input (see shellcheck -x).
We check those files separately so ignore this error for the two scripts
affected.
* Accept installation with intel-nuc in compatible string
For the OS release 6 intel-nuc gets renamed to generic-x86-64. Since
the machine name is in the OS compatible string we need to make sure
OS release 5 installation can update to release 6 despite the new
machine name.
* Change HASSOS_ID from hassos to haos
Use a rauc install-check hook to make this update compatible with OS
releases using hassos in the compatible string.
* Use home-assistant as organization in CPE_NAME
Align with Home Assistant core which uses home-assistant with a dash as
organization in CPE_NAME.
