calico node is missing contrack

We got this in the pod logs, although calico seems to come up and stuff is functional, this is certainly a longterm issue and difference from public calico so we figured we'd report it:

2021-06-02 17:29:28.888 [ERROR][50] felix/conntrack.go 116: Failed to remove conntrack flows after retries. direction="--orig-src" error=exec: "conntrack": executable file not found in $PATH ip=10.66.182.12 output=""
kubernetes.pod_name:
    calico-node-46chq

then upon comparison of public vs ironbank calico:

exec into ib:

[root@4c7faa8c8222 /]# conntrack
bash: conntrack: command not found

exec into public:

[root@d8140dc1f522 /]# conntrack
Command line interface for the connection tracking system. Version 1.4.4
Usage: conntrack [commands] [options]
Commands:

so when conntrack is needed it is not found. Its (from my understanding) not needed right away so calico will come up and cni will function for a time.
