I have a bash script with a series of whiptail menus that allows a user to setup their new system, which is Ubuntu server, with no GUI, just CLI (it's going to be a Virtual Machine image).
I'm already forcing a root login by editing /etc/default/grub and /etc/init/tty1.conf, so the user is dropped directly into the root command prompt. From there the user has to type in ./whiptail.sh to start the script and get the whiptail prompts to further setup their host.
Now, I'd like for my script to be what appears up after the the login occurs instead of the user being dropped to the command prompt. How can I do this?
