He recibido un correo avisando de que le proveedor de Internet (UnityMedia) va a realizar trabajos supuestamente para mejoras en la red.

El día 3 de Junio, las pruebas de velocidad obtienen el siguiente resultado:

El resultado desde la linea de comandos no devuelve un resultado significativamente mejor, se repite la medida cinco veces:

Cambiando la ubicación del archivo journal

He cambiado la ubicación de journal porque al intentar acceder al log de algún arranque anterior al actual aparece el siguiente error:

journalctl -b -1
Specifying boot ID or boot offset has no effect, no persistent journal was found.

mkdir -p /var/log/journal
systemd-tmpfiles --create --prefix /var/log/journal
[/usr/lib/tmpfiles.d/mdadm.conf:1] Line references path below legacy directory /var/run/, updating /var/run/mdadm → /run/mdadm; please update the tmpfiles.d/ drop-in file accordingly.
[/usr/lib/tmpfiles.d/pptp.conf:1] Line references path below legacy directory /var/run/, updating /var/run/pptp → /run/pptp; please update the tmpfiles.d/ drop-in file accordingly.
systemctl restart systemd-journald

Ahora el journal se crean en una nueva ubicación:

ll /var/log/journal/
total 0
drwxr-sr-x+ 2 root systemd-journal 28 Jun  2 19:09 9a85483ca35740a8a3e7537687fe062a

Después de reiniciar, al listar los arranques almacenados aparecen mas de uno:

journalctl --list-boots
