El nombre de host local cambia cada pocos segundos cuando NO está conectado a una red

Cuando vuelvo a encender mi computadora portátil, pero antes de conectarme a una red, recibo mensajes similares a los siguientes:

This computer's local hostname
"sojourner-896.local" is already in use on
this network. The name has been changed
to "sojourner-972.local"

Si no me conecto a una red y no hago clic en el botón "Aceptar", los nombres de host se incrementan. Si me conecto a una red (ya sea por cable o inalámbrica), los nombres dejan de incrementarse.

Restablezco el nombre de host en el panel de preferencias "Compartir" cuando los nombres de host se ubican en el rango de 5,000 a 6,000 (cada 2-3 días).

¿Alguna idea de qué podría estar causando esto?

Busqué en los registros a través de la aplicación de la consola y descubrí que los siguientes registros se generan cada vez que me desconecto de una red:

Volví a habilitar la red alrededor del segundo 10:08:14.

El proceso real que cambió el nombre de host es configd . La página de manual de configd establece que

The configd daemon is responsible for many configuration aspects of the
local system. configd maintains data reflecting the desired and current
state of the system, provides notifications to applications when this data
changes, and hosts a number of configuration agents in the form of loadable
bundles.

y

At the present time, the majority of the configuration agents (or bundles)
hosted by configd are used to establish and maintain the network
configuration.

Las páginas man muestran los siguientes archivos relacionados:

 /Library/Preferences/SystemConfiguration/preferences.plist
 /Library/Preferences/SystemConfiguration/NetworkInterfaces.plist
 /Library/Preferences/SystemConfiguration/VirtualNetworkInterfaces.plist

El archivo preferences.plist parece tener las preferencias de red especificadas por el panel de preferencias de Red en Preferencias del sistema. Hice una copia de seguridad, la eliminé, eliminé configd y realicé un reinicio de bajo nivel:

cd /Library/Preferences/SystemConfiguration/
cp preferences.plist ~/Desktop/preferences.plist
sudo rm -f preferences.plist
sudo killall configd
sudo killall configd
sudo reboot

Después de reiniciar el sistema, el sistema ya no cambia el nombre del host cada pocos segundos cuando NO está conectado a una red.

A mi alrededor, encontré un hilo en el SuperUser que podría ser de ayuda.

Es muy extraño que esto suceda cuando NO estás conectado a una red, desearía tener una mejor respuesta.

Parece que recuerdo una preferencia enterrada en algún lugar de las Preferencias del sistema que permite a la Mac obtener un nombre de host dinámico del servidor DHCP, pero por mi vida no puedo encontrar la maldita configuración. Así que o me acuerdo mal o fue algo de una encarnación de un gatito anterior.
