Strange parted behaviour

[Robert Moskowitz]

So I am making progress but saw a strange bit.

#parted /dev/sdb mkpart uboot ext3 4 516

# parted /dev/sdb print
Model: Generic- Multi-Card (scsi)
Disk /dev/sdb: 7969MB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Disk Flags:

Number  Start   End     Size    File system  Name    Flags
  1      4194kB  516MB   512MB   fat32        uboot

I formated it with:

#mkfs -t ext3 /dev/sdb1

# parted /dev/sdb print
Model: Generic- Multi-Card (scsi)
Disk /dev/sdb: 7969MB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Disk Flags:

Number  Start   End     Size    File system     Name    Flags
  1      4194kB  516MB   512MB   ext3            uboot

So why did parted mislabel the partition?
