minit-rs

PID1 init system for embedded systems in rust.

Run

cargo run -- examples/minit.json

Config format (JSON):

{
  "services": [
    {
      "name": "demo",
      "command": ["/bin/sh", "-c", "sleep 5"],
      "restart": "on-failure"
    }
  ]
}

restart supports: always, on-failure, never.

Optional per-service respawn controls:

• respawn_delay_secs: base restart delay in seconds, default 1
• respawn_max: maximum quick restarts allowed inside the respawn window, default 0 for unlimited
• respawn_window_secs: rolling window used to reset restart counters, default 60

Example:

{
  "services": [
    {
      "name": "demo",
      "command": ["/bin/sh", "-c", "sleep 5"],
      "restart": "on-failure",
      "respawn_delay_secs": 2,
      "respawn_max": 5,
      "respawn_window_secs": 30
    }
  ]
}

Send SIGTERM or SIGINT to minit-rs for graceful shutdown; it stops scheduling restarts, sends SIGTERM in reverse startup order, waits up to 30 seconds, then sends SIGKILL to any remaining children.
