Are you going to update the wiki then? Newbies need all the help they can get! If you do, make sure to mention they use RAID1! Not when they are just playing with plan9 but before they start storing precious data. On a moderen consumer disk, if you read 1TB, you have 8% chance of a silent bad read sector. More important to worry about that in today's world than optimizing disk space use. If you partition disk space, chances are, it will be used suboptimally (that is, it will turn out you guessed partition size wrong for the actual use). These days (for most people) the *bulk* of their disks contain user data so there is really no point in partitioning. Just make sure your truly critical data is backed up separately (repeat until you are satisfied).
