Just a heads up, users will start to notice a mmcblk numbering change. (specially on devices with a populated eMMC)
Due to these kernel commits:
So, starting with v4.5.3 & v4.6.x (v4.5-rc1 → v4.5.2, mmc was a dice roll…)
eMMC: mmc1 = /dev/mmcblk1
microSD: mmc0 = /dev/mmcblk0
In the past, whatever got detected “first” ended up as /dev/mmcblk0
So with microSD empty (prior to 4.5.x/4.5.3)
eMMC: mmc1 = /dev/mmcblk0
BUT now with v4.5.3+/v4.6.x+
microSD empty:
eMMC: mmc1 = /dev/mmcblk1
