Are there any good options to configure a filesystem so most activity
takes place in the RAM buffer with the flush to physical media allowed
to lag very far behind? OpenNMS does some data collection that keeps
the disk very busy. I don't want to lose the history completely in a
crash like you would with a ramdisk, but it wouldn't be a big problem if
only the last 10-30 minutes would be dropped.

The default value is 5 seconds. Zero means default. nate
