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

:If cree que de manera predeterminada, tmpwatch debería permitir acceso setattr sobre  source directory.     
:Then debería reportar esto como un error.
:Puede generar un módulo de política local para permitir este acceso.
:Do

Comment 1 Daniel Walsh 2012-07-16 17:07:19 UTC
Do you have a lib_t directory out on /tmp?  If so remove it and the avc will stop happening.

 find /tmp -context "*:lib_t:*"

Comment 2 Daniel Walsh 2012-07-16 17:08:17 UTC
Most likely you mv'd a file/directory to /tmp and now tmpwatch wants to delete it, but SELinux does not allow tmpwatch and friends to just delete any file on the system.
