The files and directories to be placed in the image.
This is a list of attribute sets {source, target, mode, user, group} where
`source' is the file system object (regular file or directory) to be
grafted in the file system at path `target', `mode' is a string containing
the permissions that will be set (ex. "755"), `user' and `group' are the
user and group name that will be set as owner of the files.
`mode', `user', and `group' are optional.
When setting one of `user' or `group', the other needs to be set too.
