the mapping of the mmc interfaces as named/numbered in the kernel has no stable relation to the device names.
This makes it very difficult to set the root=/dev/mmcblk0p2 boot arg in a stable way so that it works on all boards.
What about using filesystems labels or UUIDs? Then it doesn't matter what order the mmcblk devices are initialized in...
Hm. Does this work for µSD cards and the boot command line to define the location of the root file system?
How can I find out the UUID of an µSD card of a system that does not yet boot?
And are UUIDs the same if I create a new µSD card with the same OS on it or do they change, i.e. do I need a different boot script for every µSD card?
