Probably not. The issue is that you are dealing with the bootstrap process of a system. Typically, this is not a place where any semblance of external user interaction exists. The examples you show represent compiled-in options that are more likely part of the initial ramdisk, BIOS-level code for a specific device, or something similar. The PXE boot menu example is usually something that's being presented by an external server (via cobbler, or a similar product). There isn't an OS at that point that would likely be able to supply a python environment to use. I think we would need to better understand exactly what you are trying to build, but you are probably looking for something that would be a much lower level than python. -- David Rock da...@graniteweb.com
