Haven't we been around the houses with this 4 years ago, only to conclude that this is how Walter liked to run his fs? I can't recall what the main benefit was (other than backing up a single physical partition), but I think it was argued at the time that performance wise it would be better if all these directories were placed directly in their own independent partitions (esp. /tmp, /var and perhaps /usr). Also primary partitions which he does not seem to be using at all have a slight edge over logical. Anyway, this is Gentoo linux afterall so we can play tunes on our fs architecture more freely than other OS/distros to meet our particular needs. -- Regards, Mick
