Customize released images or recreate released images

[ghanjiboy]

Hi, I wanted to know if there was an easy way to customize an existing released image or rebuild a released image.  I know you can use the customize image option when building, but I would like to not build the latest nightly, but instead just build whatever was released. 

 

The customization I am looking to do is installing additional packages, downloading some personal python code, setting timezone and other similar settings. 

 

I searched the forums, but didn't see anything helpful, any info would be appreciated. 

 

Thanks.

you could mount the image as loopback and chroot (from an arm box)

Thanks for sharing this.  I got to mount the image and when I was trying to install iftop as in your example, apt gets stuck on Waiting for headers as in the following - any apt command, even apt update gets stuck waiting for headers.  Is this just a temporary issue or is something else wrong:

 

root@NanoPi-M4:/# apt install iftop -y

hmmm.. that's odd.  try apt clean and then possibly check on the contents of /etc/resolv.conf and make sure its got a usable DNS server.

 

otherwise don't really have any ideas.
