<disclaimer: I am with Mender> We have been evaluating OSTree as a potential building block for Mender, however the key challenges we've come across: integrating OSTree into an existing device/OS seems quite invasive - https://ostree.readthedocs.io/en/latest/manual/adapting-existing/ https://ostree.readthedocs.io/en/latest/manual/adapting-exis... block level signatures is not possible, which we feel is a requirement for an over-the-air updater rollback is not built-in and can be quite challenging to implement reliably (bootloader level) Think OSTree as more of a building block, like Git is for your development process. We might use it in the future but robustness and easy integration are our first priorities.
