Precaution when insufficient space in working-partition

A couple of people have run into this problem, of having insufficient free space in the working-partition. There are various scenarios where this is a problem.

One of those is when do a version update; the latest 'vmlinuz', 'initrd' and 'easy.sfs' may push the free space below a reasonable value. One precaution that can be taken is to reduce the history-depth; that is, how many previous versions of Easy are kept. I have inserted this code into /inc/07-new-version script, at line 28:

 #20260917 check if enough space in working-partition...
 WPfreem=$(df -m /mnt/${WKG_DEV} | grep '^/dev/' | tr -s ' ' | cut -f 4 -d ' ')
 if [ $WPfreem -lt 3000 ];then #3GB
  if [ $DEPTH_MAX -gt 2 ];then
   DEPTH_MAX=$((${DEPTH_MAX}-1))
   echo -n "$DEPTH_MAX" > /mnt/${WKG_DEV}/${WKG_DIR}.session/session1/var/local/version-history-depth
  fi
 fi

That is one step, more checks can be done.
