ArtifactReboot\_Enter\_50 script is looks to be a mender-state-script which is enabling A/B partitions during update.

```
#!/bin/sh
echo "Starting nvidia mender enter reboot redundant boot steps" >&2

set -e
num_slots=`nvbootctrl get-number-slots`
if [$num_slots != 2]; then
echo "Enabling A/B update mode using nv_update_engine" >&2
nv_update_engine --enable-ab 1>&2
fi

new_boot_part=`fw_printenv -n mender_boot_part`
new_mender_boot_part_mountpoint=/tmp/new_mender_boot_part
echo "Mounting new install partition ${new_boot_part}" >&2
mkdir -p ${new_mender_boot_part_mountpoint}
mount /dev/mmcblk0p${new_boot_part} ${new_mender_boot_part_mountpoint}
mount -oremount,rw /
cp ${new_mender_boot_part_mountpoint}/opt/ota_package/bl_update_payload_current /opt/ota_package/bl_update_payload_new
rm /opt/ota_package/bl_update_payload
ln -s /opt/ota_package/bl_update_payload_new /opt/ota_package/bl_update_payload
nv_update_engine --install 1>&2
# Should never get here, nv_update_engine will reboot on its own after successful update
echo "A failure occurred in nv_update_engine (rc $?).. nv_update_engine did not reboot" >&2
rm /opt/ota_package/bl_update_payload
ln -s /opt/ota_package/bl_update_payload_current /opt/ota_package/bl_update_payload
exit 1

```

There I see **mount rw** command. is that to write the latest image or is this causing checksum modification in my case?
