I had already applied the patch you sent me in another mail before this bug report to my local git but only now I realized that it's not working. Indeed one also needs to add --xattrs-include='*' to the tar invocation when creating and extracting a tarball with extended attributes even though the tar documentation says: > By default, when `--xattr' is used, all names are stored in the archive (or > extracted, if using `--extract'). So the patch is actually a bit bigger. I now added a test case because apparently all of this is easy to get wrong and added documentation that the user should add --xattr --xattrs-include='*' when extracting the tarball. Also the tar-in command in guestfish had to receive an xattrs:true. No worries, I already took care of it. Thanks! cheers, josch
