From 2e3b3e3a2ed7a299c29ce0460823e865f6226c45 Mon Sep 17 00:00:00 2001 From: Rich Ercolani <214141+rincebrain@users.noreply.github.com> Date: Fri, 17 Dec 2021 15:43:13 -0500 Subject: [PATCH] Workaround Debian's fake System.map behavior MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Debian ships fake System.map files by default, leading to the invocation of depmod with them to flood you with errors about missing symbols.
