           Summary: mount CONFIG_FEATURE_MOUNT_LABEL doesn't support vfat
                    labels
           Product: Busybox
           Version: 1.23.x
          Platform: Other
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P5
         Component: Other
        AssignedTo: unassigned at busybox.net
        ReportedBy: mstarr at hedonline.com

The following line in the /etc/fstab does not work with LABEL when trying to
run 'mount /boot':
LABEL=boot /boot vfat ro 0 0

The partition was created and label set using the following command (using
busybox mkfs.vfat):
mkfs.vfat -n boot /dev/mmcblk0p1

Using LABEL= with ext2 and ext4 mount points works fine.

The following busybox options are configured related to mount and vfat:
CONFIG_MOUNT=y
CONFIG_FEATURE_MOUNT_LABEL=y
CONFIG_FEATURE_MOUNT_FLAGS=y
CONFIG_FEATURE_MOUNT_FSTAB=y
CONFIG_VOLUMEID=y
CONFIG_FEATURE_VOLUMEID_FAT=y

Switching to the util-linux mount made the same /etc/fstab vfat entry result in
a successful mount.

Additionally blkid doesn't even show the vfat partition when run.
