You will not gain any of the advantages of UFS2 if you don't install from scratch, but if the system is otherwise working, you probably aren't in desperate need of those features. -- Brooks ------------------------------------------------ And likely, the filesystems you would want to use UFS2 on would be filesystems other than / (such as /home or /usr or /var), which you can accomplish by doing a backup/newfs/restore sequence afterwards, once you're happy that 5.x is working well for you. -- Matt
