Suppose kernel and initrd are on a BTRFS fs with data, metadata and system all single profile. Will a bootloader then just continue booting up a system even when there are csum errors in kernel and/or initrd files? Suppose the bootloader is grub2. -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
