If NoNewPrivileges is true, it breaks the ability to open a socket
under /var/lib/gssproxy when selinux enabled.

This works, thank you. |

@yixiangzhike IMHO it would be better to either to fix SELinux policy in your distro BTW there are bunch of systemd service on my fedora machine which have the option enabled and they work well with SELinux in the enforcing mode and even much more enabeld in SELinux policy |
It's better idea to fix selinux policy. It should allow init_t nnp transition to gssproxy_t in selinux policy.I will have a try. |
