Jim - thanks for the response. 

"zoneadm ready" doesn't work, it has to be installed first and that's what 
I'm trying to do with the attach.

If I set "zoned=off" on rpool/zones/jacob/ROOT/zbe-1 and mount it, I get 
this error:

chris at Zeb:/root# zoneadm -z Jacob attach
Log File: /var/tmp/Jacob.attach_log.puaOrn
ERROR: Failed to configure dataset rpool/zones/jacob/ROOT: could not set zoned=off.
ERROR: Failed to configure dataset rpool/zones/jacob/ROOT/zbe-1: could not set zoned=off.
                    Result: Attach Failed.

Since zoned is already off I'm not sure why it's trying to do this.

Setting zoned=on causes the filesystems to unmount

trying "attach -n" obviously returns without an error, but when I try to 
boot:

chris at Zeb:/root# zoneadm -z Jacob boot  
zone 'Jacob': ERROR: no active dataset.
zone 'Jacob': 
zoneadm: zone 'Jacob': call to zoneadmd failed
