While GPT was intended to be the only label on the disk, GEOM does not have any such restrictions. You can place any label on any geom. My suggestion would be to allocation a slice or bsdlabel partition for the GPT. Then use GPT to chop that up to meet the demands of the jails. For example, you could have: da0s1a / da0s1b swap da0s1d /var da0s1e /tmp da0s1f /usr da0s2 da0s2 could also be da0s1g. -- Brooks --=20 Any statement of the form "X is the one, true Y" is FALSE.
