I have been running this with SELinux disabled, but I'm trying to be A
Better Person by running in enforcing mode all the time. I got the following
alert while running appliace-creator. What the heck is "run lnk_file"?
----
SELinux is preventing /usr/sbin/useradd from read access on the lnk_file
run.
***** Plugin catchall_labels (83.8 confidence) suggests
***** ********************
If you want to allow useradd to have read access on the run lnk_file
Then you need to change the label on run
Do
# semanage fcontext -a -t FILE_TYPE 'run'
where FILE_TYPE is one of the following: cert_t, selinux_config_t,
# user_home_dir_t, device_t, device_t, devlog_t, locale_t,
# httpd_user_content_type, security_t, etc_t, ld_so_t, proc_t, mail_spool_t,
# device_t, abrt_t, bin_t, etc_t, base_ro_file_type, lib_t, man_t,
# etc_runtime_t, root_t, tmp_t, bin_t, cert_t, var_run_t, tmp_t, tmp_t,
# selinux_login_config_t, httpd_user_script_exec_type, textrel_shlib_t,
# etc_runtime_t, var_run_t, selinux_config_t, rpm_script_tmp_t, security_t,
# proc_t, net_conf_t, security_t, etc_t, etc_runtime_t, var_run_t, bin_t,
# var_run_t, var_run_t, useradd_t, usr_t, user_home_type, domain,
# home_root_t, etc_t, var_run_t, var_run_t.
Then execute:
restorecon -v 'run'
***** Plugin catchall (17.1 confidence) suggests
***** ***************************
If you believe that useradd should be allowed read access on the run
lnk_file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep useradd /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
