Hi,
systemd-boot counting logic requires [0] to be implemented.
Is anybody already working on this?
I am not aware of any patches
thanks for the quick response.
If not we plan to add the functionality in fs/fs.c and fs/fat - correct?
We don't have plans for it, but explaining any use cases you have might help
systemd-boot is able to do bootcounting by renaming the UKI image [0] the code that triggers the not implemented code section is here [1].
With this it is possible to have watchdog based A/B switching on systems without a writeable u-boot environment. And therefore it is a nice method to implement measured boot.
