Are questions regarding the Raspberry Pi platform topical on Server fault?
In the vast majority of cases the answer is NO. There will be a vanishingly small number of use case where Server Fault would (knowingly) accept questions about the Raspberry Pi platform.
For reference I present our discussion: https://meta.serverfault.com/questions/5586/are-raspberrypis-ever-on-topic-for-serverfault and our about.
We actively close all RPi related questions that we get as off topic
"Questions must be relevant to professional system administration. Server Fault is dedicated to professional system and network administrators. End user and enthusiast questions are off-topic (contact your system administrator or hire a professional to help you out). Please see the Help Center for more information."
