Wisdom of the ages...way back in the days when heads blew a couple times a year. Eventhough disk technology is more reliable these days, I still fully believe in keeping /, /usr, and /var as separate file systems. It's much faster and easier to rebuild separate filesystems anyway and it's easier to plan your backups. I even separate /home, and a second local filesystem that keeps all my custom stuff there because I usually d/l tarballs from the source and build for FBSD myself rather than rely on packages/ports although I do make use of them when appropriate. This makes it easier at OS upgrade time. On minis I even made /tmp it's own partition to keep temp files from killing mail, logs, and other in-house tools...and vice versa. The FBSD label editor makes it simple to partition disks at install time or when you decide to take the hit and repartition. It's always a pain to resize later but it's better to start out playing it safe. Separate partitions are your friend. Disks are cheap, throw in a few more spindles and waste a little space. Get a performance increase on SCSI or multiple IDE controllers too! The FBSD team knows this, I don't expect to seeing the default changed. This is really small stuff to worry about. ========================================================================= Jeffrey A.
