If I checked the configuration correctly, only Cubox, S500 and Udoo* don't have HAVE_UUID_SUPPORT=yes set, but AFAIK all boot scripts now load the initrd.

@Igor can you add and test root by UUID on those boards?

 

Also boot scripts for more boards could use /boot/ambianEnv.txt, I already tested it on XU4 and will try to test it on C2, will anybody be able to test it on C1 or C0 (it has much older u-boot)?

If I remember correctly there were some problems either on Cubox or Udoo, but hopefully it can work on most of the left over configurations.

OK, will check Udoo and Cubox in Monday. Cubox is critical since they use pre historic u-boot. Will check if there is working alternative.

I wouldn't call Cubox 2013.10-rc4 prehistoric because C1 uses 2011.03 

 

If there are problems overwriting existing environment variables with "env import" it may be caused by some compile-time settings.
