pub const EX_UNAVAILABLE: i32 = 69;Expand description
A required host service is unavailable (OS keyring, secret service).
G-ERR-R01: these failures used to exit EX_DATAERR, which told an agent the
input was malformed and that retrying was pointless. A locked keyring is the
opposite: the argv is fine and the very same invocation succeeds once the
service is up, so it is classified transient.
