OK, I have done this, I need to create mount points and I am not sure how to initially size.

How does everyone size /?

Since I know my /var/www/html will be large, say 300GB, I can create a mount point for at least that, but with LVM you are saying I can change the size later to increase it?

What other mount points should one have (besides swap)? No users will be storing sata on this box.
