Greetings! I've built several nanobsd systems, performed multiple upgrades (using two root file systems) and, so far, everything worked great. Enter UEFI. With UEFI boot process is handled by `/boot/boot1.efi` (uefi(8)) and gptboot(8) is no-longer in use. Therefore partition attributes, such as `bootme` and `bootonce`, are no-longer taken into account. Therefore atomic upgrades no-longer work. In fact they do work, except newly installed root file system cannot be activated, i.e. is not mounted by the kernel upon boot; instead, first root filesystem is always mounted by the kernel. Can someone suggest a way to tell `/boot/boot1.efi` which partition/filesystem to use as a root filesystem? Anyone managed to successfully use alt root filesystem with nanobsd? Dare I ask if some equivalent of `bootonce` flag is even possible?
