Hi, 4.0.6-300.fc22.x86_64: [lkundrak@fedora22-1 ~]$ unshare -r --mount --net [root@fedora22-1 ~]# mount --make-slave /sys [root@fedora22-1 ~]# mount -t sysfs sysfs /sys [root@fedora22-1 ~]# 4.2.0-0.rc6.git0.1.fc24.x86_64: [lkundrak@fedora23-1 ~]$ unshare -r --mount --net [root@fedora23-1 ~]# mount --make-slave /sys [root@fedora23-1 ~]# mount -t sysfs sysfs /sys mount: permission denied [root@fedora23-1 ~]# we use this in NetworkManager test suite, to ensure the devices we see via GUdev are the same as we see via rtnetlink. I'm wondering if this is a bug or an intended change?
