Sorry. What I was trying to say is that your test program illustrates the problem both with or without any of the boot command line options as you suggested - "ima_appraise=fix evm=fix ima_policy=appraise_tcb". Writing some other security xattr is a generic problem, whether the file is in policy or not, whether IMA or EVM are in fix mode or not. The rpm-plugin-ima should install the IMA signature regardless. SELinux doesn't usually re-write the security.selinux xattr, so the problem is hard to reproduce after installing the rpm-plugin-ima with "dnf reinstall <package>". thanks, Mimi
