Hi there,

The Devuan v6.0 excalibur release of the `devuan/devuan:latest` container started causing my GitHub Actions for the Dorothy dotfile ecosystem https://github.com/bevry/dorothy to fail. I've tracked it down to `/usr/sbin` having permissions 0777 which causes the openssh-client dependency of git to fail to install. Doing `chmod o-w /usr/sbin` resolves the failure.

You can verify it below:

docker run --rm -it devuan/devuan:latest bash
