Description Yajo 2014-07-31 08:19:18 UTC
Description of problem:
When trying to reproduce bug 1124312 with `setenforce 0`.
SELinux is preventing /bin/mv from 'rename' accesses on the chr_file .

*****  Plugin catchall (100. confidence) suggests   **************************

If cree que de manera predeterminada, mv debería permitir acceso rename sobre   chr_file.     
Then debería reportar esto como un error.
Puede generar un módulo de política local para permitir este acceso.
permita el acceso momentáneamente executando:
# grep mv /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
