I needed this for a v1.25 minikube cluster

[fmuyassarov]

hmm., I've had a successful run though on minikube with 1.25 k8s cluster...

hmm., I've had a successful run though on minikube with 1.25 k8s cluster...

I used kvm2 driver. And docker as the runtime (🫤) because of corporate https(s) proxy causes problems in minikube with containerd and cri-o

[marquiz]

Could be also fixed in the particular case (with rw host root fs) with hostPath volume type HostPathDirectoryOrCreate but I'm not that fond of this solution as it mangles the host system directories, would file on ro filesystems and we shouldn't really need /usr/src for the e2e-tests (just a small gap in kconfig detection)

tested on kvm2 driver and I could reproduce the issue + dropping host-user-src fixed the issue. I think this patch doesn't have any harm to the docker driver in minikube and instead fixes the possible ways of running E2E on minikube clusters. As such, I'm +1
