+Subject: [PATCH] systemd: allow all systemd services to check selinux status
+
+After https://github.com/systemd/systemd/commit/fd5e402fa9 most systemd
+services fail to start with:
+
+Oct 27 13:50:38 workstation-uefi systemd[1]: Starting systemd-hostnamed.service...
+Oct 27 13:50:38 workstation-uefi systemd-hostnamed[944]: Failed to open SELinux status page: Permission denied
+Oct 27 13:50:38 workstation-uefi systemd[1]: systemd-hostnamed.service: Main process exited, code=exited, status=1/FAILURE
+
+After disabling dontaudit:
+
+Oct 27 14:05:08 workstation-uefi audit[1043]: AVC avc:  denied  { read } for  pid=1043 comm="systemd-hostnam" name="status" dev="selinuxfs" ino=19 scontext=system_u:system_r:systemd_hostnamed_t:s0 tcontext=system_u:object_r:security_t:s0 tclass=file permissive=1
+Oct 27 14:05:08 workstation-uefi audit[1043]: AVC avc:  denied  { open } for  pid=1043 comm="systemd-hostnam" path="/sys/fs/selinux/status" dev="selinuxfs" ino=19 scontext=system_u:system_r:systemd_hostnamed_t:s0 tcontext=system_u:object_r:security_t:s0 tclass=file permissive=1
+Oct 27 14:05:08 workstation-uefi audit[1043]: AVC avc:  denied  { map } for  pid=1043 comm="systemd-hostnam" path="/sys/fs/selinux/status" dev="selinuxfs" ino=19 scontext=system_u:system_r:systemd_hostnamed_t:s0 tcontext=system_u:object_r:security_t:s0 tclass=file permissive=1
+
+As first step, allow all systemd services to check selinux status.
+The check for selinux status is called from mac_selinux_init() which
+is called in 16 different places, so I don't think it makes sense to
+try to list them all. Any code which wants to create a labelled file is
+likely to call mac_selinux_init().
