When using the Docker engine, build fails because the container is
unable to resolve hostnames:

I'm confused by this one as it currently works for me. That said I
thought the actual behaviour was meant to be networking is enabled by
default and explicitly disabled by the run step (which shouldn't be
pulling extra stuff down).
This was last tweaked by Daniel in 8a2390a4f47
Have the defaults for docker engine changed?

No idea as I'm not following their development, but TBH it
becomes harder and harder to use without tricks (I had to
add systemd.unified_cgroup_hierarchy=0 to kernel cmdline
to keep using it).
Maybe I should switch to podman which is the recommended
engine on Fedora.
Cc'ing Marc-André who added podman support (Daniel is in Cc).

I suppose you need need networking for git (submodule) clone?
Personally I don't require networking when running because I
share my QEMU source directory as a volume, so it never bothered
me.

I'm using podman exclusively since Docker doesn't work well with
modern distros that use Cgroups v2.

OK this probably explains it.
Ideally we could add a check for this ("modern distro" -> docker
engine not recommended) but I guess I'm the only one using this
feature on Fedora (as nobody complained) so not a problem. I'll
see how to use podman.
Thanks,
Phil.

I'm not sure we need to block it. If someone has docker installed
then its reasonable to assume they have ti working. We prefer
podman if both are installed.

From my point of view podman is the odd man out (I run upstream
docker.com packages on Debian Buster). I had to jump through some hoops
to get podman installed on my Gentoo box but I think it's currently
broken because it's Gentoo.
IOW I assume the people that really care about podman will shout if it
breaks. It would be nice if we could catch cases in the CI though.
