/test pull-kops-aws-kindnet-rhel10arm64

Trying to establish a baseline: we do want to be sure that this test fails when we don't have #17920 (or whatever fix we figure out)

[justinsb]

/test pull-kops-gce-ipalias-rhel10

[justinsb]

So that's odd .... fails on AWS RHEL10 (good) but passes on GCE RHEL10 (unexpected).

I guess it is possible that the GCE version of rhel10 is different from the AWS version, specifically about whether or not the conntrack module is installed by default.

Added a line to nodeup to print the distribution, just so we can be sure of that.

/test pull-kops-gce-ipalias-rhel10

[justinsb]

/test pull-kops-gce-ipalias-rhel10

[justinsb]

I0203 17:29:38.134697    4757 command.go:182] Detected distribution: {rpm rhel rhel10 10}

So it is rhel10

[justinsb]

/test pull-kops-gce-ipalias-rhel10

/test pull-kops-aws-kindnet-rhel10arm64

Adding dumping of /proc/modules; it won't tell us why conntrack is loaded, but it will tell us that conntrack is loaded (or other differences if it is a different module)

So the modules is interesting:

AWS rhel10 has about 40 modules: https://storage.googleapis.com/kubernetes-ci-logs/pr-logs/pull/kops/17922/pull-kops-aws-kindnet-rhel10arm64/2018767778097401856/artifacts/i-01f58c4e99be366c3/modules

GCE rhel10 has about 80 modules: https://storage.googleapis.com/kubernetes-ci-logs/pr-logs/pull/kops/17922/pull-kops-gce-ipalias-rhel10/2018767778189676544/artifacts/control-plane-us-west2-b-j2tl/modules

And in particular, GCE rhel10 has nft_ct and AWS rhel10 does not.
