Install at shutdown on the device

Hi,

Is it possible to create a deploy with pause after download and install at shutdown on the device?
I have tried the following

  • Add a mender shutdown update service that runs before mender-client at shutdown and run the script
  • In the script, use dbus-send to change all states to force_continue

It transitions to ArtifactInstall_Leave, but not to ArtifactReboot_Enter, and the deployment fails.
Is it possible to transition to ArtifactReboot_Enter during shutdown?

mender-shutdown-update.service

[Unit]
Description=Mender shutdown update service
After=mender-client.service
Requires=mender-client.service

[Service]
Type=oneshot
RemainAfterExit=true
ExecStop=/path/to/mender-shutdown-update.sh

[Install]
WantedBy=multi-user.target

mender-shutdown-update.sh (snip)

CONTROL_MAP_PRIORITY="10"
CONTROL_MAP_ACTION_FORCE_CONTINUE="force_continue"

CONTROL_MAP_FORCE_CONTINUE="{\
    \"priority\": $CONTROL_MAP_PRIORITY,\
    \"states\": { \
        \"ArtifactInstall_Enter\": { \
            \"action\": \"$CONTROL_MAP_ACTION_FORCE_CONTINUE\"
        }, \
        \"ArtifactReboot_Enter\": { \
            \"action\": \"$CONTROL_MAP_ACTION_FORCE_CONTINUE\" \
        }, \
        \"ArtifactCommit_Enter\": { \
            \"action\": \"$CONTROL_MAP_ACTION_FORCE_CONTINUE\" \
        } \
    }, \
    \"id\": \"$CONTROL_MAP_ID\" \
}"

dbus-send --print-reply --system --dest=io.mender.UpdateManager /io/mender/UpdateManager io.mender.Update1.SetUpdateControlMap string:"${CONTROL_MAP}" >/dev/null 2>&1

# Wait for transition to ArtifactReboot_Enter, but no transition
