[aaradhak]

The Fedora 40 GA is to be released on Tuesday April 23rd.

Ref: coreos/fedora-coreos-tracker#1674

let's maybe go on and change all the other container references too:

I have updated it.

@dustymabe Is this update usually done ? I didn't see this in the checklist.

LGTM

we should add it to our checklist probably

Looks like the ext.config.selinux.podman-tmpfs-context test is failing. Mind looking into that?

In the CI logs, it seems that the container exited shortly after starting. The mount command was not successfully executed.

cmd:

podman run --rm --privileged quay.io/fedora/fedora:40 \
            bash -c "mount -t tmpfs tmpfs /mnt/ && stat --format '%C' /mnt/

looks like F40 got rid of util-linux-core package which provides the mount command among other things.

just switch the test over to use quay.io/fedora/fedora-toolbox:40 to get us unblocked - it sucks because that container is much larger, but oh well.

ok, I will make the change in podman-tmpfs-context and push it.

[dustymabe]

let's try to improve the commit message of that new commit. Maybe something like:

tests/kola: use toolbox container image for selinux.podman-tmpfs-context test

In F40 the base container no longer includes `util-linux-core` so we
can't run the `mount` command. Let's just pull the toolbox container for
now, which does include it.
