Right, but that would seem to imply not calling os/exec but using something like archiver ?

You can just use io.MultiWriter(uncompressCmdStdin, progressBar).
Can be another PR.

Also, we don't have any progress bars for the copy yet either (probably mostly shown for NFS)

We can use stdlib for gzip.
Can be another PR in the future

I'm not sure if anyone is using gzip, because I think the image format supports this natively ?
Fork an external program, rather than linking everything. Keep some files compressed, such as the nerdctl-full tgz. Signed-off-by: Anders F Björklund <[email protected]>
