Issue Description
Hi
I have been flashing my drive with the Docker container and it has been perfect.
what i would like to do now is to flash two different Drives with the same setup, so that is easier i can just flash them and put them into use, with minimal setup (networking, and packages installed and more)
The issue i found was that when i went in the targetfs and chrooted inside i could add my packages and special networkings, but this wouldnt change the outside image located outside the targetfs folder.
so I thought i can delete the image and just hope the flasher will recreate the image, but it didnt happen.
so i am in a odd place at the moment, i deleted my img which i could just recreate my docker to have it back but i would like to flash my drive with my very own modifications already.
so i thought about doing
truncate -s 10G targetfs.img
mkfs.ext4 -F -L rootfs targetfs.img
and then flashing it with flash.py
but i am worried if this is the correct way forward to flash a drive with a different image, can you advise?
BR and thanks
Yuri

Dear @yuri.poledna ,
did you create new targets.img with the changes you want? If so, could you share the steps ?

As I understand, you have requirement to make changes in tartgetfs folder (like add/modify files) and they have to be reflected as is on DRIVE after flash.

Yes, @SivaRamaKrishnaNV you understood my requirement, i want to change the targetfs folder and have this reflected in the Drive after FLASH

I havent still made this new image i just thought that if i were to create it i would do it like this:
truncate -s 10G targetfs.img
mkfs.ext4 -F -L rootfs targetfs.img

but it is just a thought. I came here before i started the drive to do a sanity check if this would work because i was worried to brick the device.

what would be the workflow to flash the drive with a preset img that is different from the standard image? Should i indeed change the targetfs folder and recreate the image? or should i do something else?
Thanks
Yuri
