Read-only file volumes fail on fedora 39 with docker about crun

[giuseppe]

thanks.

Opened a PR: #1422

how have you installed Docker 25 on Fedora 39? AFAICS, the version available is moby-engine-24.0.5-1.fc39.x86_64.

it works well on Fedora 39 with moby-engine-24 for me using your same reproducer:

$ touch a.sh
$ docker run --rm --runtime crun -v $(pwd)/a.sh:/a.sh:ro registry.docker.com/library/fedora:39 echo "hello"
hello

Where Moby is configured as following:

# cat /etc/docker/daemon.json 
{
  "runtimes": {
    "crun": {
      "path": "/usr/bin/crun"
    }
  }
}

I installed with doc from docker side at https://docs.docker.com/engine/install/fedora, and installed crun with dnf

here is my daemon.json

{
  "default-runtime": "crun",
  "runtimes": {
    "crun": {
      "path": "/usr/bin/crun"
    }
  }
}

[giuseppe]

can you please please try with the version packaged for Fedora?

The packaged version from dnf works

[fedora@localhost ~]$ sudo docker run --rm --runtime crun -v $(pwd)/a.sh:/a.sh:ro registry.docker.com/library/fedora:39 echo "hello"
hello
[fedora@localhost ~]$ docker --version
Docker version 24.0.5, build %{shortcommit_cli}
