You can see entire survey report in /var/lib/sealer/data/my-cluster/rootfs/site-survey-report.yaml

Environment

• ACK Distro version: sealer-0.9.4-beta2
• OS (e.g. cat /etc/os-release):Ubuntu 18.04.6 LTS
• Kernel (e.g. uname -a):4.19.284-0419284-generic

I isure install chronyd Or ntpd and check /var/lib/sealer/data/my-cluster/rootfs/site-survey-report.yaml

I don't know the location of the executed script,like ansible ，I know how it works。

Hope for help
