Hi,
Currently the default shell is set to bash as a work around.
You can verify that by issuing
~# echo $0
If you want the appliance shell just type
~# appliancesh
Note: I have however found that if we change the default shell back to appliance shell (root:x:0:0:root:/root:appliancesh), I am unable to login to the root account. This could be a bug, we will have this validate.
