Comment 3 for bug 913856

On my system, I only see the singe "timestamps" file in /var/lib/NetworkManager. Do you have any active systems connections or VPNs active at the same time? That would explain the multiple timestamps files?

From a cursory glance, these timestamps record an active connection's last-used time so that if a disconnect occurs, NetworkManager will automatically re-connect to the right network.

Re: the fsync, my guess is removing it at worse case would cause NetworkManager to hiccup and try to connect to the wrong network if the last-used timestamp didn't actually hit the disk and the system was put to sleep/rebooted...
