I am trying to find a common way of installing a custom version of raspbian to an empty raspberry pi in the same network that boots with an empty SD Card. The most important key aspects is that the installation of the OS is automatic (No manual interaction necessary) and that the raspberry pi can fully work without being in that same network at a later time.
I have seen examples of PXE Boot and I believe it is not exactly the right option? Maybe I am wrong, but it seems that it is a way of network booting not network install, all the examples that I have seen point towards that, so I am unsure if there is a way of accomplishing the same with PXE.
Any info or help is appreciated!
