Good catch, Hugo!
The mount(8) man page says:
Mount the partition that has the specified label.
Mount the partition that has the specified uuid. These two
options require the file /proc/partitions (present since Linux 2.1.116) to exist.
This would indicate that filesystem label detection only works on partitions,
not raw devices. John - try actually creating a partition table on this disk,
and then put your filesystem on /dev/sdb1. I am guessing that you will find
that detection magically starts working after you do that.
