Linux Tar – Owner Map When Extracting

Tar has several options to affect how file and directory ownership will be stored in that tar file. For example –numeric-owner, or –owner-map. These options directly affect how the tar file will be extracted, or what will be done on extraction assuming we run extraction as root.

• Without options, tar will find corresponding group/user in current system and set the ownership to that group/user even if the uid/gid are different then they were when creating the archive.
• With –numeric-owner, the extraction will always set uid/gid to the same as it was when we created the archive
• With –owner-map, we can provide our own mapping for users/uids, but only when we are creating the archive. Using this option does nothing when extracting the archive.

These options are great, but I need to be able to affect what tar does with ownerships when extracting, at the time I am extracting the archive, not when I am creating the archive. The –owner-map seemed like a perfect solution to me, until I found it does nothing when it is provided when extracting.

So my question is: Is it somehow possible to control with what ownerships will tar extract the files and directories, at the time when we are extracting the archive?

I could not find anything relevant. As a solution I attempted to create chroot environment with /etc/passwd and /etc/group that would ensure the correct mapping, and then extract the tar archive under the chroot, but it did not work. I assume it is because the chroot still takes users and groups from host system somehow, but it feels like this could lead to a solution.

I would appreciate any kind of help or ideas, even if they are hacky (I think replacing /etc/passwd and /etc/group in the system I am extracting in would work, but that is not acceptable for me).
