Soft restart doesn't work

[dgkPBP]

You're right. Excellent.
When I ran blkid with the SD inserted, It didn't list SD partitions. I moved the SD to USB/sd dongle and lo and behold, the labels are the same!

Question: would changing the label on the SD make it bootable? I would think so. Question is how do I change the label on the SD? 

Thanks. You have solved a puzzling  mystery. 

Code:

[admin@pbp ~]$ sudo blkid
