[RndTbl] Partitioning in Linux

Well, not really partitioning. I know how to do that. At work today, the question of how to set up some Linux servers arose. To put it in some kind of context, when I install Ubuntu Linux (server), by default it creates a small /boot partition, the creates a LVM partition with a / ext4 partition and a swap partition inside of that. Is that optimal? Recommended? Some would say that /home, /tmp, /var and others should reside in separate partitions/filesystems. Discuss. :-) Thanks for any input! Kevin
