During an upgrade of my Debian Squeeze, the following message was displayed on my screen :
libraw1394-11 (2.0.5-1) …
Creating device node /dev/raw1394… .udevdb or .udev presence implies active udev. Aborting MAKEDEV invocation.
This is just a notification, not a warning message. In the past, the creation of any device was made by makedev. Now, all this sub-system is replaced by udev.
