Steps to Reproduce:
1. Boot computer.
Actual results: SELinux violation.

Expected results: No SELinux violation.

Additional info:

SELinux is preventing /usr/bin/systemd-tmpfiles from getattr access on the file /var/tmp/kdecache-root/icon-cache.kcache.

*****  Plugin catchall_labels (83.8 confidence) suggests  ********************

If you want to allow systemd-tmpfiles to have getattr access on the icon-cache.kcache file
Then you need to change the label on /var/tmp/kdecache-root/icon-cache.kcache
# semanage fcontext -a -t FILE_TYPE '/var/tmp/kdecache-root/icon-cache.kcache'
where FILE_TYPE is one of the following: sysctl_crypto_t, passwd_file_t, locale_t, var_auth_t, krb5_conf_t, etc_t, file_t, proc_t, sysfs_t, man_t, config_home_t, tmp_t, wtmp_t, cpu_online_t, systemd_tmpfiles_exec_t, non_security_file_type, lockfile, pidfile, tmpfile, samba_var_t, abrt_t, samba_etc_t, ld_so_t, lib_t, net_conf_t, sandbox_file_t, cpu_online_t, abrt_helper_exec_t, security_t, rpm_var_cache_t, faillog_t, systemd_tmpfiles_t, httpd_cache_t, proc_net_t, textrel_shlib_t, etc_runtime_t, user_home_type, rpm_script_tmp_t, rpm_var_lib_t, file_type, httpd_sys_rw_content_t, ld_so_cache_t, file_context_t, abrt_var_cache_t, etc_t, cert_t, sosreport_tmp_t, machineid_t, rpm_tmp_t, admin_home_t, sssd_public_t, abrt_var_run_t, selinux_config_t, krb5_host_rcache_t. 
Then execute: 
restorecon -v '/var/tmp/kdecache-root/icon-cache.kcache'

*****  Plugin catchall (17.1 confidence) suggests  ***************************

If you believe that systemd-tmpfiles should be allowed getattr access on the icon-cache.kcache file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
allow this access for now by executing:
# grep systemd-tmpfile /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Please remove


then it works. We added fixes to prevent this.
