Armbian-install: disable Docker when installing images

[igorpecovnik]

Description

Stop Docker system running Armbina-install to prevent weird results and to speed up. Does it make sense?

How Has This Been Tested?

• Manual test, disabling and installing to eMMC, reboot, works

weird results and to speed up. Does it make sense?

Weird results all the time, as armbian-install does an rsync of a running system -- many things can be open and change during the rsync. I think Docker (containerd, really) and its overlay2 filesystem might just be wors-er than most, but the wierdness can happen with many other things.

The "correct" way of doing this involves creating a temporary initrd and kexec'ing into a new kernel and initrd while leaving the original image unmounted, so that it can be copied without anything open or running on it. It is a huge endeavour though.
