Description ToFabricio 2017-07-13 17:37:30 EDT

Description of problem:
SELinux is preventing systemd from 'read' accesses on the lnk_file /var/lib/snapd/snap/atom-cwayne/current.

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

If cree que de manera predeterminada, systemd debería permitir acceso read sobre current lnk_file.     
Then debería reportar esto como un error.
Puede generar un módulo de política local para permitir este acceso.
Do
allow this access for now by executing:
# ausearch -c 'systemd' --raw | audit2allow -M my-systemd
# semodule -X 300 -i my-systemd.pp

Snappy is not part of Distribution SELinux policy. Closing.
