Some commands and information to help with Bookworm OS

Manually create a system image

sudo bash /var/www/add_on/Image_Tools/image_utils/image-backup

Reload systemd manager configuration.

This command should not be confused with the reload command.

sudo systemctl daemon-reload

Start the service mnt-pibackups.mount See here

sudo systemctl start mnt-pibackups.mount

Stop the service mnt-pibackups.mount See here

sudo systemctl stop mnt-pibackups.mount

For each automount unit file a matching mount unit file must exist, which is activated when the automount path is accessed. Example: if an automount unit mnt-pibackups.automount is active and the user accesses /mnt/pibackups the mount unit mnt-pibackups.mount will be activated.

A typical use case for automount units is mounting file systems (e.g. on remote or removable or encrypted media) that are not required during the boot process and may slow it down, or that may be unavailable at boot, but that you still like having managed by systemd.

sudo systemctl enable mnt-pibackups.automount

show the state of all services

sudo systemctl status

show the state of all services with descriptions

sudo systemctl;

To see failed services

sudo systemctl –failed

To attempt to restart failed services

sudo systemctl reset-failed

bookworm uses NetworkManager rather than WPASupplicant to manage the wifi connection. You can issue the command ‘sudo nmtui‘ from the commandline to initiate a graphical interface to setup the connection.

For some reason the BT.helper service doesn’t start on my Raspberry PI 3B Therefor add this line to the /boot/config.txt file

sudo nano /boot/config.txt

add the following to the end of the file and save

dtoverlay=disable-bt #disable Bluetooth
