Source: dnprogs A while ago, it was suggested to remove the decnet kernel support, here: https://lore.kernel.org/lkml/20220731190646.97039-1-step...@networkplumber.org/
No negative feedback was received, so maybe this will happen. When it happens, dnprogs will be unusable in (stock) Debian. (dnprogs upstream also appears abandonded.) I would suggest removing dnprogs, if not for bookworm then in the trixie cycle. Chris
