[Feature request] Beyond OEM mode

I've been experimenting with Ubiquity's OEM installation (on neon User).
What I was trying to achieve was:

· Install neon on a test system.
· Customise it to my liking
· Make a tarball of it that I could send to my customers, friends and relations - so they could install it as such.

What I managed to achieve was:
. Install it (in OEM mode)
· Boot it and customise it (even though it did not copy the personal settings to /etc/skel
· Successfully copy the OEM install (prepared for "shipping") to another partition and boot it.

After "minimal setup" on the final install, the newly created user's settings disappeared.
All installed apps were there, but not configured.
Copying the settings to /etc/skel before "shipping" worked. Why the installer doesn't do that to start with is a bit... mysterious.

What I could not achieve was:
· Copy the install partition to a different machine and boot it successfully.
Boot fails with multiple hardware issues.

Since the (let's call it) mini-installer at first boot does say "configuring hardware", I was hoping the first boot itself would be somewhat "hardware-agnostic" - like the ISO boot is. It isn't.

I was hoping someone on this team would want to look into making a "universal OEM-mode installer" feature.
Which I believe would open a world of possibilities for Linux installs - not least of which finally creating an option to install it without "live media" - or rather obscure and failure-prone grub-ISO-booting - which IMO should definitely be available.
