I added to the cmdline.txt instructions
to correct issues with a sata-usb interface and to change the mac address.
The quirks are effective for the boot, but at a reboot, the cmdline edit is gone and the sata-usb interface does not work properly anymore. When I check, I see that the edit is lost in the cmdline.txt file.
How can I prevent the overwriting of the edit?
From reading various suggestions, I have the impression, that the first cmdline.txt is setting things up and booting afterwards uses a reduced set of the arguments. Is this correct? Details?
