wic/wks boot using labels instead of partitions

wic/wks boot using labels instead of partitions

[Mark Hatle]

Is there a way to tell the _generated_ fstab to use labels to boot and not hard 
coded partitions?

If I remove the --ondisk <device> attribute from the wks file it defaults to 
/dev/sda.

What I tried was:

part /boot --source bootimg-partition --fstype=vfat --label boot --active 
--align 4 size 16
part / --source rootfs --fstype=ext4 --label root --align 4


If I manually add --no-fstab-update to the wks entries and add the following to 
the system default fstab:

LABEL=boot   /boot  vfat  default  0  2


This works.  But I'd like to automate it within the wks.

(Alternatively I could use uuid instead of label booting, but either case, I 
need to only boot with the uuid or label -- not the partition as the location of 
the disk can change.)

--use-label

This should do it.
