Enum SystemdState 

pub enum SystemdState {
    Running,
    Degraded,
    Starting,
    Unavailable(String),
}

What systemctl is-system-running said.

Variants

Running

Fully up.

Degraded

Up, with at least one failed unit. Usable: the product’s own unit is what matters, and service status reports it separately.

Starting

Still coming up. Usable for the same reason, and the alternative — refusing during the first seconds after a cold start — would make the preflight flaky rather than strict.

Unavailable(String)

Not systemd, or systemd is not the init here. Refused.
