All of it is built from source, it's just that the current build process is not easy to audit. The build by definition needs to happen on multiple platforms or cross compiled, a root cert needs to be setup in the windows installer at boot time, and so on.

I agree that this is not an ideal way to boot an ISO, but the general public is unlikely to ever need a multiboot USB stick. I like this project enough to perhaps contribute.
