How to download custom image from linode on my PC?

As far as I know the image must be deployed to a Linode and then boot the linode vps into Rescue mode and use dd:

I don't do it exactly like this though. I usually boot with an extra blank ext4 disk so that I can dd the image disk to an img file first, then I download img file. Also if I made changes to the image and want to re-upload as a custom image I can do that by just using gzip on the img file while still in the Rescue mode and then installing python to the Rescue OS for the linode-cli.
