chcon: não é possível aplicar contexto parcial ao arquivo sem rótulo enquanto instala o nagios com o SELinux

Estou configurando o núcleo do Nagios no CentOS com SELINUX = reforçando.

Eu tento correr

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

conforme sugerido no manual , mas recebo estas mensagens de erro:

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

Alguma idéia de como evitar esses erros?

Você precisa rotular novamente os arquivos com o tipo certo de selinux:

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