k3s-kernel

Version	2026.225.1707
Repo	box/github.com/opencharly/layer-k3s-kernel:v2026.237.457

Ensures the full distro kernel is installed and reboots the venue so it boots it. The Arch cloud image ships a minimal kernel without overlayfs or iptables/netfilter — k3s’s containerd and kube-proxy both fail on it (“failed to mount overlay: no such device”, “iptables is not available on this host”). The deploy’s system upgrade installs the full linux package, but the running kernel stays the minimal one until a reboot. This candy installs the full kernel explicitly and requests a reboot (RebootStep, emitted last) so the k3s-server checks run against a kernel that can actually run k3s. Only the vm deploy reboots (rebootVenueAndWait, deterministic boot_id gate); pod/OCI/kubernetes skip the RebootStep and local targets skip + warn.

Acceptance plan

This candy’s plan: — the runnable spec charly check executes against a live deployment. check: steps are idempotent probes; run: steps change state.

Intent	Step
check	the full kernel package is installed — the precondition the reboot boots it
