AI Analysis

●●●BangerWizardryBig BrainShip It

Landlock + seccomp-BPF sandboxing with preset configs beats rolling your own isolation.

Strengths
  • Rootless design with user namespaces eliminates setuid helper attack surface
  • Preset configurations for build, install, agent, GPU use cases reduce misconfiguration risk
  • Live forking via COW reflinks clones running jails in milliseconds for incremental builds
Weaknesses
  • Linux 5.13+ requirement excludes older enterprise environments still on LTS kernels
  • GPU passthrough marked experimental, not production-ready for ML workloads yet
