Bug#498074: ud: Don't sync() every filesystem every two minutes

[Sami Liedes <sliedes@cc.hut.fi>]

Package: ud
Version: 0.7.1-21
Severity: normal

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.
