I compiled my own kernel and installed a Debian Linux on /dev/md0 on my My Cloud Mirror disks. I can boot it if I manually change the bootargs and bootcmd when I interrupt U-boot autoboot (pressing space and 1 alternating).
Now I want to make my changes more permanent since I have no intention to move back to the original setup of many partitions and all.
Is it possible after I have set all my parameters correctly so I’m very sure it boots to save the U-boot settings with saveenv. My goal would be that I can install Debian just on mdadm mirrored drives without the need to interrupt autoboot and without the need to partition the drives exactly how the device shipped.
So shortly: once a working U-boot setup, will saveenv make my changes permanent?
Maybe it would be a good idea to save the output of printenv first so I can roll back later if I really feel the need to do so?
