Ruben Fiszel f8467f38c8 fix: prevent cross-tenant DNS poisoning via writable /etc in nsjail (#9194)
* fix: bind /etc resolver files read-only in nsjail sandboxes

* docs(nsjail): explain why per-file /etc resolver binds are load-bearing

The explicit /etc/hosts, /etc/resolv.conf and /etc/hostname binds look
like removable duplication of the read-only /etc bind above them. They
are not: on Kubernetes those files are separate kubelet bind-mounts on
top of /etc and nsjail's read-only remount is non-recursive, so without
these shadow binds they stay writable and a job can persist cross-tenant
DNS poisoning for the pod lifetime. Comment guards against a future
"dedup cleanup" silently reintroducing the vulnerability.
