well, i meant the filesystem UUID that is used for root=, the kernel
translates it to /dev/root since a few years by default (we even
released fstab-less readonly images for the TI pandaboard in 2012 that
relied on this fact).

ah, so systemd can make out even more info from the GPT data !
thanks i'll surely take a look at that (though these naming games from
the systemd people that make things sound like an improvement start to
scare me. their "PredictableNetworkInterfaceNames"  that we have to
battle with nowadays are clearly a lot less predictable than just having
eth0/wlan0 hardcoded across the board ;) )
