is it possible to remove the script when you login over SSH as root.
So that when you log in you are at a bash prompt?
Get to the bash prompt via the default script menu then change the default shell to bash:
root@zeroshell root> which bash
root@zeroshell root> chsh -s /bin/bash admin
Exit bash and log out. Now when you log in you will be directly in bash. This will last until you reboot the box.
I do this so that I can use the FUSE ssh filesystem setup to mount my Zeroshell box for drag-and-drop access from my MacBook.
