Old kboot use the file system label to search a root partiton.
YellowDog kboot is old kboot based. So you can boot your Linux.

But current kboot does not use the file system label.
Current kboot configuration file search algorithm is as follows.

      - device search priority
          built-in BD drive, USB mass storage, built-in HDD

      - check if the media has more than one partitions, if no, try to
        examine boot configuration file on the media.

      - Otherwise, it checks if the partition is marked as "active"  or 
not in 
        ascending order. In the case of "active', try to examine boot 
configuration
        file on the partition.

      - check if format of the media(or partition) meet one of following;
          ext2, ext3 (on USB mass), FAT16/32 (on USB mass) or ISO9660 (on 
optical)
        (Caution) kboot mount ext3 file system by using "-t ext2" option

      - try to mount the selected media(or partition) and check a boot
        configuration file named either /etc/kboot.conf or /ETC/KBOOT.CNF. 

        If the boot configuration file exists, kboot read it. If the boot 
        configuration file does not exist, kboot umount the selected media
        (or patition) and check the next media(or patition).

New kboot try to mount /dev/ps3da1 to '/' and seach '/etc/kboot.conf' 
file.
But '/boot/etc/kboot.conf' does not exist, so you can not boot your Linux.

This setting is wrong.
Correct setting is as follows.

nfsboot='tftp://192.168.1.1/pxelinux.0 root=/dev/nfs  ip=on 
nfsroot=192.168.1.1:/ '
                                       -       -
