Description of problem:
Since upgrade from F26 to F27 Beta
SELinux is preventing boinc_client from 'map' accesses on the fichier /var/lib/boinc/slots/4/boinc_mmap_file.

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

If vous pensez que boinc_client devrait être autorisé à accéder map sur boinc_mmap_file file par défaut.
Then vous devriez rapporter ceci en tant qu'anomalie.
Vous pouvez générer un module de stratégie local pour autoriser cet accès.
Do
allow this access for now by executing:
# ausearch -c 'boinc_client' --raw | audit2allow -M my-boincclient
# semodule -X 300 -i my-boincclient.pp
