@mason-org/triage If you want to try this out I'd appreciate it! It should be fully seamless, but needs to manually be enabled:

require("mason").setup {
  firewall = {
    enabled = true
  }
}

LGTM

A note on the "system packages" available in https://github.com/mason-org/mason-system-registry. The idea is for every package to include a version scope in the package name itself. In the case of sfw the package name is sfw@latest. Should more packages be available in the future, for example Python and Node, these would be separate packages named like:

• node@18
• node@20
• node@latest
• python@3.12
• python@3.11
