Comment 38 for bug 2048473

@ubuntushop (g-info-l) ; I guess I'm lucky then. All devices I have to install have an Azerty BE keyboard, which is provided. I also have another use case then you I guess: (345 devices for 12-year olds and 300 for 15-year old)

I'm happy with workaround 1. I described in #32

All settings come from autoinstall.yaml and a postinstall script I trigger with
  late-commands:
    - cp /postinstall.sh /target/
    - curtin in-target --target=/target -- chmod +x /postinstall.sh
    - curtin in-target --target=/target -- bash /postinstall.sh

The postinstall.sh script adds some settings in /etc/gnome-initial-setup/vendor.conf, so the gnome-installer now only asks for username, password and network if not available.

skip=language;keyboard;timezone;privacy

Further the postinstall script installs salt-minion and its repository and starts that. This installs the rest of the software and changes some settings, but that is outside the scope of this report.

But may be the postinstall script can install some extra keyboard layouts?
