I am a new SUSE person, so do not know something clearly. I do know RedHat has a program called kudzu that runs early in the booting process that will remove and add devices to the system, to keep the devices and the database clean.
But in suse don’t have kudzu, i want to know in SUSE which program do this?>:)>:)>:)>:)
Thats a very good question. AFAIU openSUSE increasingly uses hal/udev to provide this function dynamically, while some devices (eg network cards) are more statically configured via YaST. I know this anwer could be expanded on considerably more than I have explained…
I am not sure what you mean by this. But the device special files in /dev are generated anew every boot (and as /dev is a special fs residing in memory it is lost on system halt). That generating of the /dev contents is done by the udev Deamon (udevd) as mentioned above. No need to worry about forgotten entries in /dev.
