The funny thing what i recognized too as i looks more in /lib/udev/devices is that there the loop devices has "root:root, 0666" but in my /dev they have "root:disk, 0660". The reason seams that because i use my own kernel package with "CONFIG_BLK_DEV_LOOP=y" instead of "CONFIG_BLK_DEV_LOOP=m". But again, i was only wondering not afraid about it.-) And to say something good at the end about the last updates: Thanks a lot for activating VIRTIO in kernel26. See you, Attila
