Re: [U-Boot] Partition UUIDs in U-Boot and Linux (blkid vs 'part list')

Hi,

I find that blkid provides different output from 'part list' and I'm not sure why:

"part list" prints partition UUIDs (from the partition table), whereas I /think/ blkid prints filesystem UUIDs (from the fs superblock).

The kernel will accept either on its cmdline root= parameter, but you have to tell it which you're using, e.g. root=PARTUUID=partition_uuid, or IIRC root=UUID=fs_uuid.
