And tested on Stretch/Sid:
Stretch: BeagleBone Black + gpt partitioned mmc
debian@arm:~$ sudo blkid
/dev/mmcblk0p1: LABEL="rootfs"
UUID="27a1bbfa-c648-4d86-ad30-b7169527ac36" TYPE="ext4"
PARTUUID="0d9b735f-9ffe-4058-85d8-0af6eb0a901e"
/dev/mmcblk0: PTUUID="aa80930d-d880-4e30-9240-19e78863e112" PTTYPE="gpt"
debian@arm:~$ cat /proc/cmdline
console=ttyO0,115200n8 root=UUID=27a1bbfa-c648-4d86-ad30-b7169527ac36
ro rootfstype=ext4 rootwait
debian@arm:~$ cat /proc/cmdline
console=ttyO0,115200n8 root=LABEL=rootfs ro rootfstype=ext4 rootwait
debian@arm:~$ cat /proc/cmdline
console=ttyO0,115200n8
root=PARTUUID=0d9b735f-9ffe-4058-85d8-0af6eb0a901e ro rootfstype=ext4
