This will allow units (scopes/slices/services) to override the default systemd-oomd setting DefaultMemoryPressureDurationSec=. The semantics of ManagedOOMMemoryPressureDurationSec= are: - If >= 1 second, overrides DefaultMemoryPressureDurationSec= from oomd.conf - If is empty, uses DefaultMemoryPressureDurationSec= from oomd.conf - Ignored if ManagedOOMMemoryPressure= is not "kill" - Disallowed if < 1 second Note the corresponding dbus property is DefaultMemoryPressureDurationUSec which is in microseconds. This is consistent with other time-based dbus properties.
