Hey pali,
good you stepped in here

A bit offtopic question to you here:
do I understand your comment about limitation of 8 partitions (in fact 7, as mmcblkx also counts as one) right this way that we have a limit of 8 per device (so 16 for N900 with SD) or is it a total limit of 8 for eMMC and SD together?
I just ask as I stumbled upon this limit with N9 partitioning where I tried to make 9 partitions (on internal and only mmcblk device). and sfdisk reported everything fine. but I could only see up to mmcblk0p7...
