Given this, it's at least prudent to make sure that it logs to a remote host only, or sparsely. Making /tmp (and possibly /var/tmp) ramdisks is also useful. It might not be common to get that many writes to the same sector consistently, but considering a few easy steps can greatly extend te life of the device, it might be worth it. -- - Kevan Benson - A-1 Networks
