Its also really nice because it allows you to keep a well managed file system (with /usr and /home and /usr/local and everything else all in their own partitions) but not have to guess how big you want each of these things initially because you can just grow them when necessary. AIXs "move stuff around the disk" (don't know the features real name) is nice too because it allows you to grow swap then make sure its all contigious and in the middle of the physical disk... alex
