Installation can proceed as usual, but presumably you don't already know the name of the user you're installing for. In all install cases you'll need to at least take the steps of picking a language and keyboard mapping for the installer (in case you need to also enter other information, such as the OEM ID we ask for to differentiate OEM install batches, crypto password, network authentication to reach a mirror, etc.). The difference is that when you do an OEM install, you do the file copying phase, reboot into an "OEM preparation" environment, so that you can do any further customization of the actual setup (pre-installing some software that wasn't done automatically, checking to make sure everything is as it should, etc). Then you can tell the system that everything is ready, and reboot into the "real" system customization phase that is done by the end user: user name, hostname, timezone, and all of that jazz. Doing so via oem-config or GNOME Initial Setup could just as well be a decision left to the OEM provider. > 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.

That said, there's already an easy workaround, you can choose exactly what keyboard mapping you want before you pick "Try" or "Install" if you booted in BIOS mode (I know, that doesn't work in UEFI yet).

You can already set automatic/custom hostnames as an enterprise policy via preseeding or via DHCP. For factory systems, it seems to me like there is no benefit in setting any hostname at all (or if there is, please let me know); it's a user decision what they want to call their machine. In an enterprise setting, I would usually not expect people to use an OEM-type install (even your 'minimal' proposal), but rather preseed the installation parameters and only leave to users the few decisions that would make sense -- in an enterprise setting, this often doesn't even include the username. Making users further go through GNOME Initial Setup should already be possible by configuring the final system via a preseed (ie. install the right package, but the right files in so it starts when you log in). My concerns with this are mainly that many of the "advantages" listed in the design document [1] for Initial Setup are already covered by ubiquity as far as I can tell (speed of install, being able to do unattended installs, etc.); with the benefit that it's not tied to any particular desktop environment: ubiquity (oem-config) should work just as well for any desktop environment, without requiring the use of GNOME software (some flavours may not want to use some, for various reasons). We let the end user make customization decisions as late as possible so that we don't block the installation unnecessarily while the user picks a hostname or username. In my experience that tends to fit nicely in the time it takes to complete the file copy (but otherwise, you're not blocking the end of the installation much either). I'm all for improving ubiquity by removing code duplication, doing a big cleanup in that monstrous codebase, and simplifying the installation process in general, but right now it seems to me like GNOME Initial Setup would only solve this for a fraction of our users. Could you come up with a code branch that does what you want and knows to install GNOME Initial Setup, or with a pre-made image that mocks up how you see things, so that we could play with it? As for the flavours, aside for Kubuntu where shipping Initial Setup would be bad (take up more space on their image and look very odd); how do you feel about having such an Initial Setup step? How would it look? [1] https://wiki.gnome.org/Design/OS/InitialSetup / Matt
