For some reason, dnf install still succeeds, but when the selinux tests
fail with:

All this is fixed once policycoreutils is added to the list of RPMS so
it is updated (from 3.9-3.el10 to 3.10-1.el10) during the same
transaction.

Bump bats to the version from Fedora 42 (used in "fedora" job), so we
have the same version everywhere.
This also fixes an issue introduced by commit d31e6b87 (which forgot to
bump bats in GHA CI), and adds a note to the yaml in order to avoid the
same issue in the future.

We are seeing a ton on flakes on almalinux-8 CI job, all caused by criu
inability to freeze a cgroup. This was worked around in criu [1], but
obviously we can't rely on a distro vendor to update the package.
Let's use a copr (thanks to Adrian Reber!)

In a nutshell:
- use git-core instead of git;
- do not install weak deps;
- do not install docs.
This results in less packages to install:
- 25 instead of 72 for almalinux-8
- 24 instead of 90 for almalinux-9

It now comes with container-selinux 2:2.224.0-1.module_el8+712+4cd1bd69,

Add a workaround for a problem of older container-selinux not allowing
runc to use dmz feature. If runc sees that SELinux is in enforced mode
and the container's SELinux label is set, it disables dmz.
Add a build tag, runc_dmz_selinux_nocompat, which disables the workaround.
Newer distros that ship container-selinux >= 2.224.0 (currently CentOS
Stream 8 and 9, RHEL 8 and 9, and Fedora 38+) may build runc with this
build tag set to benefit from dmz working with SELinux.
Document the build tag in the top-level and libct/dmz READMEs.
Use the build tag in our CI builds for CentOS Stream 9 and Fedora 38,
as they already has container-selinux 2.224.0 available in updates.
Add a TODO to use the build tag for CentOS Stream 8 once it has
container-selinux updated.

This is a test case to demonstrate the selinux vs dmz issue.
The issue is, runc calls selinux.SetExecLabel and then execs the
runc-dmz binary, but the execve is denied by selinux:

Vagrant failed to initialize at a very early stage:

The problem is, vagrant cache overwrites newer plugin with an older one.

A version of vagrant available from the stock repos (2.2.19) is too old
and contains a bug that prevents downloading Fedora 38 image (see [1]).
Use packages from hashicorp repo, which currently has vagrant 2.3.4.
This resolves the problem of downloading the latest Fedora image.
Also, vagrant-libvirt plugin from Ubuntu repos is not working with
vagrant from hashicorp, so switch to using "vagrant plugin install".
The downside it, this takes extra 4 minutes or so in our CI, and I
am not sure how to cache it or speed it up.

This variable is used in curl to download a go release, so we are using
the initial Go 1.19 release in Cirrus CI, not the latest Go 1.19.x
release.
From the CI perspective, it makes more sense to use the latest release.
Add some jq magic to extract the latest minor release information
from the download page, and use it.
This brings Cirrus CI jobs logic in line with all the others (GHA,
Dockerfile), where by 1.20 we actually mean "latest 1.20.x".

As reported in [1], in a case where read-only fuse (sshfs) mount
is used as a volume without specifying ro flag, the kernel fails
to remount it (when adding various flags such as nosuid and nodev),
returning EPERM.
Here's the relevant strace line:
> [pid 333966] mount("/tmp/bats-run-PRVfWc/runc.RbNv8g/bundle/mnt", "/proc/self/fd/7", 0xc0001e9164, MS_NOSUID|MS_NODEV|MS_REMOUNT|MS_BIND|MS_REC, NULL) = -1 EPERM (Operation not permitted)
I was not able to reproduce it with other read-only mounts as the source
(tried tmpfs, read-only bind mount, and an ext2 mount), so somehow this
might be specific to fuse.
The fix is to check whether the source has RDONLY flag, and retry the
remount with this flag added.
A test case (which was kind of hard to write) is added, and it fails
without the fix. Note that rootless user need to be able to ssh to
rootless@localhost in order to sshfs to work -- amend setup scripts
to make it work, and skip the test if the setup is not working.

GCP images description at [1] claims that:
- For CentOS 8 and CentOS Stream 8, the PowerTools repository is
enabled.
- For CentOS 7, EPEL is enabled.
Apparently,
- we do not need epel for centos-stream-8;
- powertools is not enabled on centos-stream-8 despite [1].
Anyway, the less yum commands the better, as we have seen those fail
sometimes due to occasional networking problems etc.
