However you may implement this feature please make sure that it takes care of the availabel disk space! Most people do only have limited space on their root partition and by making numerous snapshots your hard drive will be clobbered soon. Besides this the feature should stop automatically or ask for elder snapshots to be deleted before the max. drive fill reaches a certain percentage (f.i. 80%). As soon as your root partition gets filled by 100% you may not even be able to boot from it. Honestly thinking I can imagine there being an automatic restoration point for the last update only many consecutive updates being condensed for the same auto-restoration point on a single day, only. Anyway please do not leave many automatic restoration points hanging around. Elmar
