Hi Mark, Thanks again for your attention and response.

I have never seen this. What I saw on Debian and Ubuntu was
https://github.com/lxc/lxc/issues/3221#issuecomment-600171973
which was unusable but not a segfault.

The cause was that I did not install libpam-cgfs package.
You are welcome to close this, though this seems a minor bug to me.
I have no idea if this is an upstream issue.

Best regards, Ryutaroh
