I have trouble with the idea that a swap partition is "never dropped" once it is accessed, especially in light of the following: osiris# cat /proc/meminfo total: used: free: shared: buffers: cached: Mem: 48283648 42934272 5349376 28479488 1650688 16846848 Swap: 94957568 0 94957568 MemTotal: 47152 kB MemFree: 5224 kB MemShared: 27812 kB Buffers: 1612 kB Cached: 16452 kB SwapTotal: 92732 kB SwapFree: 92732 kB osiris# swapoff /dev/hda2 osiris# cat /proc/meminfo total: used: free: shared: buffers: cached: Mem: 48283648 42909696 5373952 28483584 1650688 16846848 Swap: 0 0 0 MemTotal: 47152 kB MemFree: 5248 kB MemShared: 27816 kB Buffers: 1612 kB Cached: 16452 kB SwapTotal: 0 kB SwapFree: 0 kB If one really wants to avoid swap, why wouldn't one simply not have any swap partitions? > > > > > -- > To UNSUBSCRIBE, email to [EMAIL PROTECTED] > with a subject of "unsubscribe".
