Make sure you have plenty of swap, though. If the bits in /var aren't life or death (or at least production mail-serve= r) you can get by with it being mounted on a volatile filesystem (like tmpfs or mdmfs) and backed up occasionally (via cron or similar). If you absolutely can't afford to lose even 5 minutes of /var's past you'd be better off mirroring. I generally put / & /usr on the same disk, they're reasonably small & written to very little, if you symlink /usr/obj, /usr/src, & /usr/ports. --=20 --
