chcon: no se puede aplicar el contexto parcial a un archivo sin etiqueta al instalar nagios con SELinux

Estoy configurando el núcleo de Nagios en CentOS con SELINUX = enforcing.

Trato de correr

chcon -R -t httpd_sys_content_t /usr/local/nagios/sbin/

como se sugiere en el manual , pero recibo este mensaje de error:

chcon: can't apply partial context to unlabeled file `cmd.cgi'
chcon: can't apply partial context to unlabeled file `trends.cgi'

chcon: can't apply partial context to unlabeled file `config.cgi'

¿Alguna idea de cómo evitar estos errores?

Debe volver a etiquetar los archivos con el tipo de selinux correcto:

semanage fcontext -a -s system_u -t httpd_sys_script_exec_t /usr/local/nagios/sbin/*
