Sounds good. It would be nice to have at least one interface that isn't web-based, but that's not vital.

Are we talking things like net-setup? What exactly are we talking about using here?

That's probably a good idea, but really sucks for the people that don't know what they want. That was the nice thing about the current GLI, being able to click that "Recommended" button. Of course, you could limit the "Recommended" concept to only work with known-good partitioning schemes. For example: blank drive - we know we can partition this 1 primary partition (and free space) - we know we can handle this ...and that's about it. You would cover a vast majority of the users with this option. I would think (using the GTK+ installer as an example) that having something like the current partitioning screen + an "Advanced" button, which drops to a shell to allow the user to partition manually, using pretty much anything that they want (LVM, EVMS, DMRAID, MDRAID) would cover all the bases. I think having it as "opt-in" on the "easy" screen and only allowing known-good configurations should resolve most of the issues with partitioning.

I like it.

Absolutely. I think the "configure and forget" aspect of the installer is one of its greatest strengths.

One thing that I have never understood is why all of GLI is in python. Take catalyst as an example. It uses python for the places where python does best and uses bash for the rest. It makes it very easy to understand when it calls out to smaller, interchangeable scripts for sub-tasks. I'm not saying that this is what the GLI needs to do, but it could definitely make things easier, and also reduce the memory footprint of GLI, when loaded.

That's OK by me, too. We'll get some flak for it, I'm sure, but at this point, I don't think we can do *anything* without getting flak, so our best course of action is to just do what we think is best.

Well, if you jokers didn't discuss everything on IRC... ;] -- Chris Gianelloni Release Engineering Strategic Lead Alpha/AMD64/x86 Architecture Teams Games Developer/Council Member/Foundation Trustee Gentoo Foundation
