摘要： Methods and apparatus for associating partitions in a computing device are disclosed. An example method includes, loading an operating system (O/S) kernel partition (kernel partition) and identifying one or more root filesystem (rootfs) partitions that are compatible with the loaded kernel partition. In the example method, the one or more compatible rootfs partitions are identified by comparing a set of compatibility bits of the loaded kernel partition with respective sets of compatibility bits of a plurality of rootfs partitions of the computing device. The example method still further includes selecting a rootfs partition from the one or more identified compatible rootfs partitions and loading the selected rootfs partition.

摘要： Configurations providing a non-zero threshold for verifying a root file system of an operating system stored on blocks of a boot storage are disclosed. In particular, the root file system is verified during a boot sequence for the operating system. For each block of the root file system of the boot storage, the subject technology verifies a respective block of the boot storage. A counter tracking a number of verification failures is incremented if the block fails verification. In some configurations, the subject technology determines whether the counter meets a predetermined non-zero threshold. If the counter meets the predetermined non-zero threshold, the root file system is marked as corrupted. A recovery mode for the operating system is then initiated. If the counter does not meet the predetermined non-zero threshold, the operating system is reset in order to verify the root file system during a subsequent boot sequence.
摘要翻译：公开了提供用于验证存储在引导存储器的块上的操作系统的根文件系统的非零阈值的配置。特别地，根文件系统在操作系统的引导顺序期间被验证。对于引导存储器的根文件系统的每个块，主题技术验证引导存储器的相应块。跟踪多个验证失败的计数器如果块验证失败，则会递增。在一些配置中，主题技术确定计数器是否满足预定的非零阈值。如果计数器满足预定的非零阈值，则根文件系统被标记为已损坏。然后启动操作系统的恢复模式。如果计数器不满足预定的非零阈值，则操作系统被重置以便在随后的引导序列期间验证根文件系统。

摘要： A system and method is disclosed for locking down a capability of a computer system. Hardware instructions initiate a sequence of boot cycles to launch a computer operating system on a computer-enabled device. During the boot cycles, multiple levels of boot code are verified. Each verified stage of boot code verifies a subsequent stage of boot code. If the subsequent stage of boot code cannot be verified, the verified stage locks a capability of the computer so that the subsequent stage of boot code cannot modify the capability.
