…tstack#70198) Default SALT_ONEDIR_HARDEN=1 on 3009.0+ so each daemon's writable state lives under per-daemon /var/lib/salt/<daemon>/{home,extras-<py>} directories and /opt/saltstack/salt stays root:root 0755. Set SALT_ONEDIR_HARDEN=0 in /etc/default/salt-setup (DEB) or /etc/sysconfig/salt-minion-setup (RPM) to restore the legacy chown -R salt /opt/saltstack/salt behavior for one release; the opt-out is deprecated and will be removed in a future release. Runtime salt-pip and the onedir _salt_onedir_extras .pth hook honor SALT_EXTRAS_DIR so packages installed via salt-pip continue to be importable by the daemon after the packaging layer relocates the extras tree. Postinst / posttrans scriptlets migrate any populated legacy /opt/saltstack/salt/extras-<py>/ contents into the per-daemon location once, idempotent no-op otherwise.
