System76 would like to use GNOME Initial Setup for user configuration.
Currently, there is duplication with Ubiquity.
We propose changing Ubiquity to add a “minimal” mode, triggered by a kernel
parameter (a flag similar to how OEM install is triggered now). This enables
flavors to use whichever version makes sense for them. System76’s Pop!_OS and
the elementary OS team are interested in using “minimal”. Minimal might be
attractive to Ubuntu w/ GNOME as well.
“Minimal” will contain the least amount necessary to install the OS. We also
prefer off-line installs with minimal which would remove options to download
updates or install 3rd party software during install. This requires adding
language packs to the iso when using minimal.
Minimal screens:
Welcome/Language Select - change: add KB Layout [1]
Installation Type - change: move hostname here [2]
If full disk encryption is chosen, Choose Security Key screen.
--Timezone: we’d like to remove timezone but Ubiquity is crashing when we do
so. More investigation is necessary.
[1] KB layout currently comes after “Installation Type”. Users can’t set their
layout before typing a full-disk encryption password. Moving KB layout forward
would fix this. However, Ubuntu uses the first Welcome Screen to display both
language and “Try Ubuntu” or “Install Ubuntu”. A couple of ideas:
1. Boot to a live environment with a “Install Ubuntu” icon on
the desktop.
2. For a “complete” Ubiquity install, move KB layout after the
Welcome Screen.
[2] Hostname is currently on the “Who are you?” screen. It uses the username
and DMI information to populate the hostname. We propose using the same DMI
information, adding 4 hexadecimals to the end (a checksum of the MAC address
“Galag-Pro-A8F3”), and moving the hostname up to the “Installation Type”
screen. This enables “minimal” installs to set the hostname and business
customers can install the OS on multiple machines, with automatic or custom
hostnames, then give the computer to their user for account setup.
