Bug#498074: ud: Don't sync() every filesystem every two minutes
While figuring out what kills the performance of my system under
certain heavy disk loads, I figured out ud does AFAICT entirely
unnecessarily a full filesystem sync() on every filesystem every time
it updates the uptime record, which is once every two minutes.
A fdatasync() at most should be easily enough for the application.
