What is the current recommended way to build a custom Debian installer? A preconfigured installation ISO would save me quite a lot of time, except for the fact that I don't know how to do it well. I would like to make some for x86_64 and armhf.
That would work, except that wasn't my question. Which way do you personally recommend using. I have tried a few build scripts and the results were not good even though it did boot.
This is the best way, but not the easiest way. It requires a little bit of reading, and a bit of trial & error without giving up. Once you get it, then it becomes very easy. Obviously it can be very advanced also. It depends how much you want to customize your images. http://live.debian.net/manual/3.x/html/live-manual.en.html#1
