/proc/sys/kernel/yama/ptrace_scope is already set to zero, and SELinux is already disabled via the kernel command line.

To answer Pavel’s related question, here is the kernel version:

5.0.3-200.fc29.x86_64 (mockbuild at bkernel03.phx2.fedoraproject.org) (gcc version 8.3.1 20190223 (Red Hat 8.3.1-2) (GCC)) #1 SMP Tue Mar 19 15:07:58 UTC 2019
