Owner and group of an hdiutil attached disk image

It's known that a disk image attached with ignored owners (vsdbutil -c prints disabled) will have owner and group to match whatever user is accessing the disk. However, the following bit from diskutil's man says it may behave differently: > The behavior is different when disk images are attached. With disk > images, the owner of all files in a filesystem mount for which owners > are ignored is the user attaching the disk image. The attaching owner > is also used when creating new files. I cannot replicate this. Despite the attaching user, owner and group are always set to match whomever is accessing disk's files.
