Trigger script after provision

[reflexcameras]

Is there a way I could automate triggering a script after each provision? I would like to edit the hostname and add a linked deploy key to the image I am using. I am making the deploy keys on the provisioning device

Yes - a somewhat-trivial modification to the sb-provisioner script would perform the changes you want for now - but the intent is to introduce a range of hook-scripts at various points through the process to make this more straightforward.

After

rpi-sb-provisioner/service/rpi-sb-provisioner.sh

Line 768 in 5c89daa

mount -t ext4 "${ROOT_DEV}" "${TMP_DIR}"/rpi-rootfs-img-mount ${DEBUG}

, the root file system is mounted at "${TMP_DIR}"/rpi-rootfs-img-mount, and you're free to make changes to your copy to facilitate your use case.

One warning, however - making changes there may foul the hot-path detection (which relies purely on sizes and file presence). In such a mode, you would likely want to not set RPI_SB_WORKDIR, and instead regenerate your provisioning asset for each device.

Great, thankyou, I will try this and make sure I don't set the WORKDIR so that it regenerates on each provision.

If I installed the sb-provisioner via apt where will I find the rpi-sb-provisioner.sh to edit?

Installed from apt, you'll find it in /usr/local/bin, as specified in our install file:
