Thanks. I found another tutorial (from RedHat) which basically says: 1. Implement your service, give it a new SELinux type and run it. 2. Collect all the complaints from SELinux. 3. Use audit2allow to convert them to rules. 4. Repeat until you don't get any more complaints. And I cannot believe my eyes. Is this *really* the way to implement SELinux policies? It seems like a joke to me. Isn't there any notion of inheritance or something like that? Like, I want my type to have the permissions of this other type plus these two more rules. Also, audit2allow tells me that a bunch of rules can be substituted by just flipping a boolean, but I cannot include booleans in the .te file? Everything is very confusing to me. -- Iñaki Úcar _______________________________________________ devel mailing list -- devel@lists.fedoraproject.org To unsubscribe send an email to devel-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org
