Re: [Libguestfs] Cargo edition problem with Debian 11

Oh, I misread your initial mail. I saw "Debian" in the subject line and assumed you were talking about packaging. But you weren't. This is happening in CI for every platform. There's a straightforward way to fix the problem for Cirrus CI, the one that runs after we mirror to Github. But it requires an extra step, and I'm not sure how to configure that for the .gitlab CI stuff. I'll submit a partial PR and ask for help with the gitlab CI part. You aren't using gitlab CI to build release artifacts, are you?
