File 0093-Don-t-exit-0-if-killing-epmd-is-impossible-because-t.patch of Package erlang
From 161630f3e1e870dee50cd5c5161e9f09ebe9066b Mon Sep 17 00:00:00 2001 From: Stephan Renatus <srenatus@chef.io> Date: Mon, 3 Apr 2017 11:15:39 +0200 Subject: [PATCH] Don't exit 0 if killing epmd is impossible because there's living nodes Living nodes will make `epmd -kill` fail, but there's no way to tell except by looking at the commands output. With this change, the exit code will be 1 to indicate failure.
