Looking at the source for keepdir in ebuild.sh it seems that -R and -r are trying to be supported to create .keep files in a tree of directories. However, "${D}" is missing on the find command so it looks at the build host instead of the image when looking for directory names.

keepdir doesn't pretend to support -r now, and also that function doesn't seem to make much sense; why would you want to keep a whole tree?
