Container isolation not working under CentOS 7

Hi,

I’m currently fiddling with Docker on my workstation running OpenSUSE Leap 15.1 and on a public sandbox server running CentOS 7. It looks like I found an inconsistency related to container isolation under CentOS 7. I’ve sent a detailed description of the problem to the CentOS mailing list:

Any suggestions?

Cheers,
