modifying filesystems while suspended (or better: between snapshot creation and restore time) is dangerous, because after resume, the on-disk state is probably different than what the kernel thinks it is. There are prominent examples of people who "just booted knoppix to get a file off that partition" on a suspended system. Usually it ends with nasty file system corruption and data loss (since it might do unnoticed for some time and the longer it takes to show up, the heavier the corruptions will probably be). I _believe_ that it is probably "mostly harmless" for this atime change, and i am not sure if the cure is better or worse than the disease, but there is a potential problem. I am no filesystem expert at all, so take all this with a grain of salt. -- Stefan Seyfried QA / R&D Team Mobile Devices | "Any ideas, John?"
