The ubiquity doesn't call `ubunut-drivers install` to install (at least) nvidia drivers but workaround by copying configurations[1].

It's because calling the "ubuntu-drivers install" might be an unexpected call flow (calls "ubuntu-drivers install" in chroot stage of ubiquity) and the solution may need to change a lot[2]. To implement it will be better in coming release and workaround (by copying configurations) in previous releases.

However, to use "ubuntu-drivers install" is the correct/final way to make sure the logic of selecting/configuring the configurations for proprietary drivers.

I'll suggest to have "jjj/impish/hirsute/focal" series here to make sure we have solution(workaround) for each series (workaround in I/H/F and have the final solution in "jjj(22.04)").
