Create backup image from USB / SDCARD. How to run run armbian-tf on next run

[araczkowski]

Hi,
I'm creating a backup image from USB/SD Card with my programs. I'm using Gparted to shrink the partition and have smaller image.
Now the problem is that when I run the system from the backup I want to automatically resize the partition to the whole space on SD card. This can be done via armbian-tf command. But the question is how to execute this command automatically when the new backup is started for the first time?
Thanks for the answer

echo "yes" >/root/.no_rootfs_resize

amlogic-s9xxx-armbian/build-armbian/armbian-files/common-files/usr/sbin/armbian-fix

Lines 207 to 212 in f0af993

	# Maximize root partition size
	todo_rootfs_resize="/root/.no_rootfs_resize"
	[[ -f "${todo_rootfs_resize}" && "$(cat ${todo_rootfs_resize} 2>/dev/null | xargs)" == "yes" ]] && {
	armbian-tf 2>/dev/null &&
	tolog "89. Root partition resized successfully..."
	}

thanks @ophub I found this flag and I set it to yes

echo "yes" >/root/.no_rootfs_resize

but after new boot the flag is still yes but the size not adjusted

there is a flag armbian_firstrun maybe this one should be set?

armbian_firstrun="usr/lib/armbian/armbian-firstrun"

I also tried

touch /root/.not_logged_in_yet

but still no root partition resized

when the armbian-fix is executed?

[ophub]

When build armbian os add:

echo "yes" >/root/.no_rootfs_resize

If there is this file in the armbian system, it will be executed automatically when the system starts for the first time. It can be executed manually later: armbian-fix

[araczkowski]

to run the armbian-tf automatically after system starts (first time after shrinking the image) I added to the /etc/custom_service/start_service.sh

# Maximize root partition size
todo_rootfs_resize="/root/.no_rootfs_resize"
[[ -f "${todo_rootfs_resize}" && "$(cat ${todo_rootfs_resize} 2>/dev/null | xargs)" == "yes" ]] && {
    armbian-tf 2>/dev/null &&
    echo "[$(date +"%Y.%m.%d.%H:%M:%S")] Maximize root partition done!" >>${custom_log}
}

Now I'm doing:

1. run system, add packages and adjust settings
2. set the flag no_rootfs_resize to yes
3. shrinking the image in Gparted
4. burn the shrinked image to new USB/SD CARD
5. run the system from new image

and it works, after first boot, we have -> Maximize root partition size

thanks @ophub for your help 👍
if you see better way to do this just please let me know
