From 01801b131f21f126b341f0db069727d6f9bd8d2e Mon Sep 17 00:00:00 2001 From: Stefano Brivio Date: Tue, 21 Feb 2023 18:03:49 +0000 Subject: selinux: Switch to a more reasonable model for PID and socket files Instead of restricting PID files to /var/run/passt.pid, which is a single file and unlikely to be used, use the user_tmp_t type which should cover any reasonable need.
