title: "Use clone instead of fork on pvf" doc: - audience: Node Operator description: | For validators: Adds a new, optional security capability. Most modern Linux machines should support it, otherwise you will get a warning like: "- Optional: Cannot call clone with all sandboxing flags, a Linux-specific kernel security features: not available" If you are already running in a secure environment such as a container, this may conflict with our security features; your only option may be to ignore the warning. Otherwise, it is recommended to upgrade your Linux version! migrations: db: [] runtime: [] crates: - name: polkadot-node-core-pvf - name: polkadot-node-core-pvf-prepare-worker - name: polkadot-node-core-pvf-execute-worker host_functions: []
