Description of problem:
I just turn off SELinux. Reboot and then enable SELinux. Reboot and have this conflict
SELinux is preventing chronyd from 'open' accesses on the file /var/lib/chrony/drift.

*****  Plugin restorecon (94.8 confidence) suggests   ************************

If необходимо исправить метку.
Стандартная метка для /var/lib/chrony/drift: chronyd_var_lib_t.
Then можно выполнить restorecon.
Do
# /sbin/restorecon -v /var/lib/chrony/drift

If you want to allow chronyd to have open access on the drift file
Then необходимо изменить метку на /var/lib/chrony/drift
Do
# semanage fcontext -a -t FILE_TYPE '/var/lib/chrony/drift'
where FILE_TYPE is one of the following: abrt_helper_exec_t, abrt_var_run_t, bin_t, boot_t, cert_t, cgroup_t, chronyd_exec_t, chronyd_keys_t, chronyd_tmpfs_t, chronyd_var_lib_t, chronyd_var_log_t, chronyd_var_run_t, cluster_conf_t, cluster_var_lib_t, cluster_var_run_t, courier_exec_t, cpu_online_t, dbusd_etc_t, dhcpc_state_t, etc_runtime_t, etc_t, exim_exec_t, fail2ban_var_lib_t, file_context_t, fonts_cache_t, fonts_t, gpsd_tmpfs_t, hostname_etc_t, krb5_conf_t, ld_so_cache_t, ld_so_t, lib_t, locale_t, machineid_t, man_cache_t, man_t, mandb_cache_t, net_conf_t, passwd_file_t, postfix_postdrop_t, prelink_exec_t, proc_t, rkhunter_var_lib_t, rpm_script_tmp_t, samba_etc_t, samba_var_t, sendmail_exec_t, shell_exec_t, sosreport_tmp_t, src_t, sssd_public_t, sssd_var_lib_t, sysfs_t, system_conf_t, system_db_t, system_dbusd_var_lib_t, systemd_logind_var_run_t, systemd_passwd_agent_exec_t, systemd_passwd_var_run_t, systemd_systemctl_exec_t, textrel_shlib_t, timemaster_tmpfs_t, timemaster_var_run_t, usr_t.
Then execute:
restorecon -v '/var/lib/chrony/drift'


*****  Plugin catchall (1.44 confidence) suggests   **************************

If вы считаете, что chronyd следует разрешить доступ open к drift file по умолчанию.
Then рекомендуется создать отчет об ошибке.
Чтобы разрешить доступ, можно создать локальный модуль политики.
Do
allow this access for now by executing:
# ausearch -c 'chronyd' --raw | audit2allow -M my-chronyd
# semodule -X 300 -i my-chronyd.pp
