 Hmm. This seems caused by:
 
 > .if ${USE_GPT} != "no"
 > BOOTDISK_UUID=`${TOOL_GPT} ${GPT_TIMESSTAMP} ${WORKMBR} show -i 2 | ${TOOL_AWK} '/^GUID/ {print $$2}'`

 and

 ${WORKFSTAB} needs to depend on ${WORKMBR} image file to get
 a UUID created by ${TOOL_GPT} with ${GPT_TIMESTAMP}?  Umm.
 (note GPT/UEFI part was not implemented by me)
 
 I wonder if we can calculate the UUID from ${GPT_TIMESTAMP}
 without an actual image, but anyway we need some dummy targets
 that checks and removes ${WORKMBR} if its size is different
 from ${IMAGESECTORS}?
 
 Needs make(1) guru..
