a=$(ps -eo args 2>/dev/null | grep -E '^([^ ]*/)?etcd( |$)' | head -n 1)
[ -n "$a" ] || a=$(cat /etc/kubernetes/manifests/etcd.yaml 2>/dev/null | tr '\n' ' ')
d=$(printf '%s\n' "$a" | tr ' "' '\n\n' | sed -n 's/^--data-dir=//p' | tail -n 1); d=${d:-/var/lib/etcd}
[ -d "$d" ] || exit 1
p=$(stat -Lc %a "$d") || exit 1
if [ $((0$p & 0077)) -eq 0 ]; then echo compliant; else echo "noncompliant: $d mode $p"; fi
