You are running in an environment where sandbox isn't working properly. Please tell us more about your setup.

Well, I guess this is a hardened/selinux problem. Or in other words: genkernel would need a selinux policy. I don't use SELinux so I cannot help. Maybe adding SANDBOX_WRITE exception for /proc/self (?) like https://gitweb.gentoo.org/proj/genkernel.git/tree/gen_funcs.sh?h=v4.0.0_beta19#n1376 would be enough (https://wiki.gentoo.org/wiki/SELinux/Gentoo_profiles#SANDBOX_WRITE)? Of course you can disable sandbox usage in genkernel with "--no-sandbox" argument but...
