Abstract:
The embodiments set forth a technique for restoring a computing device to an operable state when a software update renders the computing device inoperable. According to some embodiments, a snapshot of a file system volume is automatically generated prior to executing the software update. When an issue is detected with the software update—e.g., the computing device freezes, the computing device cannot boot into an operable mode, etc.—the computing device can (1) automatically enter into a restoration mode, and (2) restore the file system volume to its previous state in accordance with the snapshot. In this manner, the issues caused by the software update are entirely mitigated, and the computing device can transition back into an operable state.
