/opt/so/saltstack/default holds the source for every root-executed script -- /usr/sbin, the reactors, _runners/_modules/_beacons, the master engines and salt-relay.sh -- plus every state the root master renders. SOC mounts /opt/so/saltstack rw as uid 939, so root-owning /usr/sbin alone was not enough: the next highstate would copy attacker-controlled bytes out of the tree into the root-owned destination and run them. SOC never writes under default/, it only reads it. Every SOC write targets local/, which stays socore-owned, as does /opt/so/state. No mode is enforced on default/ -- SOC reads that tree, and 750/640 would break its config load. Also stops copy_new_files(), so-saltstack-update and setup from chowning the tree back to socore, and replaces preserve: True in soup_scripts.sls, which carried uid/gid in from the /tmp staging tree and would have undone the ownership before the first post-soup highstate.
