From 063ab0370b49fc0477e70f02c20d5667734580a4 Mon Sep 17 00:00:00 2001 From: vasilito Date: Mon, 27 Jul 2026 15:39:10 +0900 Subject: [PATCH] =?UTF-8?q?local/docs:=20correct=20=C2=A715.3=20to=20note?= =?UTF-8?q?=20openssh=20sed=20requires=20local=20fork?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit After operator feedback: editing mainline recipes/net/openssh/recipe.toml directly is a policy violation (per AGENTS.md: 'DO NOT edit files under mainline recipes/ directly — put patches in local/patches/'). This commit reverts that incorrect approach in the documentation and correctly states the proper fix path: 1. Create local/recipes/net/openssh/ as a Red Bear fork recipe that uses the same upstream tar with a Red Bear patch file (local/patches/openssh/01-ipv6-capability-detect.patch) 2. OR implement IPv6 in netstack/relibc (root cause fix, tracked elsewhere) The current sed workaround in recipes/net/openssh/recipe.toml remains in place, documented as a known gap. This commit is documentation-only.
