[SoaS] Problem with Mirabelle and USB Boot

[Marc Karasek]

OK,

To prevent it name the sticks Fedora prior to putting the image on 
them.  (This step should be added to the online instructions.)

Now, if you did not change the name and need to modify the syslinux.cfg, 
change the following lines: (you will have a different UUID#)

   append initrd=initrd0.img root=live:UUID=3D4E-8E71 rootfstype=vfat rw 
liveimg overlay=UUID=3D4E-8E71 quiet  rhgb rd_NO_LUKS rd_NO_MD

   append initrd=initrd0.img root=live:UUID=3D4E-8E71 rootfstype=vfat rw 
liveimg overlay=UUID=3D4E-8E71 quiet  rhgb check

to

   append initrd=initrd0.img root=LABEL=FEDORA rootfstype=vfat rw 
liveimg overlay=LABEL=FEDORA quiet  rhgb rd_NO_LUKS rd_NO_MD

   append initrd=initrd0.img root=LABEL=FEDORA rootfstype=vfat rw 
liveimg overlay=LABEL=FEDORA quiet  rhgb check

I tested this fix and it works.
