Description of problem: SELinux is preventing bwrap from 'getattr' accesses on the archivo /proc/sys/user/max_user_namespaces. ***** Plugin catchall (100. confidence) suggests ************************** Si cree que de manera predeterminada se debería permitir a bwrap el acceso getattr sobre max_user_namespaces file. Then debería reportar esto como un error. Puede generar un módulo de política local para permitir este acceso.
