On some operating systems, the very system call that should wait until all unwritten data for a file has been flushed - fsync() - might actually return befo...

See LXF 114 p48, 'Banish Your Daemons' Runlevels are defined levels in which a linux operating system can start. Daemons (or services) are scripts/programs that run in the background constantly (like apache or mysql are services that are always running) and are usually executed at startup by the defined runlevel. Runlevels are identified by a number from 0 - 6, but each linux distribution may use those numbers a bit differently. Basically a runlevel determines which daemons to execute at startu...
