Hey, I work for Northern.tech, developing update software for embedded Linux devices.
I have a question about GRUB's environment block: This block is not checksummed, and hence I reckon it can become corrupt if power is lost in the middle of a write. This is an important safety criterion for us, so we've been thinking of developing environment block checksumming as an extension to the existing save_env and load_env commands. The most likely approach will be to grab X amount of bytes at the end of the block and use these for the checksum. This would also allow us to fall back to an earlier environment file if the current one is corrupt, hence implementing redundancy. Is this something that the GRUB project would be interested in? We want to upstream this if possible, since we think many people may benefit from this. -- Kristian _______________________________________________ Grub-devel mailing list Grub-devel@gnu.org https://lists.gnu.org/mailman/listinfo/grub-devel
