Explain that to my bootloader. Kernel needs root= on a command line.

Well, for usb, order is not guaranteed, for SATA, it worked. So that's
a regression in v4.8-rc1.
Yes, /dev/disk/by-* is good idea, but this broke my boot, probably
broke some scripts that used for a long time... and kernel may not
break working systems.
