OK part of my confusion is that 'grub2-mkconfig' does not work when called directly. Doing that results in a malformed grub.cfg. What is the correct way, on atomic builds, to recreate the grub.cfg? How does rpm-ostree do this? The closest I get to a command is 'ostree admin instutil grub2-generate' but this fails with ** ERROR:src/libostree/ostree-bootloader-grub2.c:154:_ostree_bootloader_grub2_generate_config: assertion failed: (grub2_boot_device_id != NULL) Aborted (core dumped) I'm not sure what it wants.
