From 13b9b9c3136a2d4859f6da799950e28d688e7dd0 Mon Sep 17 00:00:00 2001 From: Christophe Besson Date: Sat, 3 Oct 2026 15:06:44 +0200 Subject: fix(packaging): node and hub stop and clear their bytecode on removal A node left running after removal recompiled bytecode into the shared venv, and meshbay-common's cleanup ran too late for the node and hub directories: dpkg warned that they were not empty.
