Hi @jokemanfire. Thanks for your PR.

I'm waiting for a containerd member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes-sigs/prow repository.

Do you have specific use cases for XZ and bzip2? Same as discussed before (#10241 (comment)), I'd prefer to avoid new dependencies (compress/bzip2 and the xz CLI) unless we have specific needs for them.

(Note that XZ was the subject of a recent backdoor, so I would encourage the use of alternative compression libraries and algorithms as opposed to xz and lzma.)

I think this is just a user-friendly issue, I pursuit of smaller image packages sometimes. Add more type compressed file type if more convenient for me , that I can choose the compressd type in different scene . Also, prepare for a higher compression ratio image pull.
In my opinion, and I think Decompress should let containerd do but not the cri tool, This will make the supported encoding files uniform, and many other CRI tools do not require additional code. As my add code core/images/archive/importer.go.
This is just my idea.

In example :
xz is the smallest type when I wrap it. I just want to use it in import. such like ctr i import busybox.tar.bz2.....
2.0M 5月 24 21:57 busybox.tar.bz2
2.1M 5月 25 08:28 busybox.tar.gz
1.7M 5月 17 20:26 busybox.tar.xz
Users can manually decompress before import it , but I find moby support it ,it will be more convenient.
XZ backdoor such like didn't introduce to Linux distribution version. And use xz cli , giving the choice to the operating system , But we can carefully consider it.
