I thought it was going to be part of https://github.com/coreos/bootupd but I'm not sure of the status. In an idea universe there'd be an "origin" copy of /boot and /efi, and the sync tool would sync from "origin" rather than treating one of the satellite drives as a sort of primary or canonical copy. It would be super cool to have the option to push a NEWEFI directory with the updated binaries, and use an EFI BootNext variable. If the next boot fails, the update didn't work, and the reboot automatically reverts to the EFI directory. If the boot works, the the tool could atomically replace EFI/ with NEWEFI/ to complete the update. Further, it would be neat if this tool can partition and format, so that a drive can have these partitions wiped and replaced or enlarged and repopulated as needed. But that is a lower priority. -- Chris Murphy
