# Possible problem with overlayfs:

#     when using overlays deleting existing in the lower layer dirs can cause error (hopefully it gets fixed someday):

#       example: 

#           * /mnt/sda1 exists in lower layer: /tmp/rootfs.ro/tmp

#           * upper layer is mounted to /

#       # rmdir /mnt/sda1

#       # mkdir /mnt/sda1

#       mkdir: cannot create directory '/mnt/sda1': Operation not supported
