My wife and I have done two of the book nook kits now. Trust me when I say making it an evening activity for two halves the difficulty.

The one you have done looks amazing - IMO the mistake work.

As someone who uses Debian everywhere - it’s just the opposite end of the spectrum from Arch for (non security) updates. Getting any OS into a bad state is trivial if your not paying attention. I still don’t understand why they make a rolling release version.
