Add [isolation] config section for job isolation layers (#99 PR 5/6)#105
Conversation
Adds configurable isolation settings so operators can enable/disable each isolation layer independently: ```toml [isolation] setuid = true # Run jobs as submitting user (requires root) namespaces = true # PID + mount namespace isolation seccomp = true # syscall whitelist (blocks ptrace, mount, bpf) landlock = true # filesystem access control (kernel 5.13+) ``` All layers default to enabled. Each degrades gracefully when the kernel doesn't support it or spurd isn't running as root. Closes: part of #99 Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

The BPF syscall whitelist needs validation on production workloads before enabling by default. Gate behind env var until the [isolation] config section (PR #105) provides proper operator control. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
