Adding more persistent disk images

[kl522]

by "copy the /UNIONFS counterpart" do you mean the entire system as opposed to "only the changes?" on my test system /UNIONFS consists of around 2GB data, whereas /KNOPPIX-DATA is only 140MB....

is there a better way to do what i am trying to do (use the persistent overlay image knoppix-data.img on a read-only media)?

sincerely,

Sorry it wasn't clear to me what you are trying to accomplish. But I am only saying that if you copy /KNOPPIX-DATA but omitting the dot-wh-dot files, you will have inconsistent packages.
