SELinux is preventing /bin/mount from 'remount' accesses on the filesystem .

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

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

All mount commands are blocked in non privileged containers.

You would probably need to run this with --privileged
