 I also wanted to add this fourth recipe, which I created
 after code inspection and testing:
 
   newfs /dev/rwd1a
   mount_ffs /dev/wd1a /mnt
   touch /mnt/test
   tail -f /mnt/test &
   echo test >> /mnt/test
   mount_ffs -o update,ro /dev/wd1a /mnt
 
 This is important because just having the file open
