I'm trying to create my own iso image based on Ubuntu 12.10 and I've got several questions.
1) How can I add user using preseed? I tried to do it this way, but I still have to enter the password in the graphical installation:
d-i passwd/user-fullname string kiosk d-i passwd/username string kiosk d-i passwd/user-password password 123 d-i passwd/user-password-again password 123 d-i passwd/user-uid string 2020 d-i user-setup/allow-password-weak boolean true
2) Is it possible to change a set of screenshots and the text that is displayed in the graphical installer?
3) How can I handle late_command in preseed file (after installation I want to configure system, install deb-packages, etc.) I tried to do it this way:
d-i preseed/late_command string mkdir /target/install/; cp -R /cdrom/extra/* /target/install/; chroot /target chmod +x /install/postinstall.sh; chroot /target bash /install/postinstall.sh
