Feature: Don't display redundant error messages on execute failure

単一のサーバーで 'logrotate -f /etc/logrotate.conf' を実行して失敗を再現し、報告された SSHKit::Runner::ExecuteError および SSHKit::Command::Failed メッセージを調査します。これらのエラーがどこで表面化するかを追跡し、その後、関連するエラーの1つがコマンド、終了ステータス、stdout、stderrを保持し、同じ失敗を3回繰り返していないことを確認します。

Showing the same error in three different ways seems redundant. Is it possible to collapse into one?

The second one looks most relevant.

Background: It occurred when I run

execute 'logrotate -f /etc/logrotate.conf'

on a single server, where the postrotate script for logrotate exits with a failure status.
