From 34b5c4a8cda98f50e000be78d39ec7fb9e93898e Mon Sep 17 00:00:00 2001 From: Malin Date: Thu, 12 Mar 2026 18:31:57 +0100 Subject: [PATCH] fix: replace fake sudo with real sudo package MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Real sudo uses env_reset by default, which naturally clears PKG_EXECPATH. This lets the child binary's pkg bootstrap start fresh and load the embedded main module correctly — no more 'Cannot find module' crash. Removes the sudo-wrapper.sh hack entirely; the real sudo package handles all edge cases (environment cleanup, privilege semantics) correctly.
