Description Victor Engmark 2007-05-15 11:10:02 UTC

The current handbook, chapter 8.4, explains the kernel option "GEOM_GPT" as enabling "a large number of partitions on a single disk." How many?

More importantly, this is not sufficient information for anybody who has performed an installation with the default partitioning. Will disabling this option break a default installation?

Also, is this option necessary in order to /create/ partitions, just to /use/ them, or both?
