TODO - it seems, that custom device file removal is now working? A simple man page is attached. thanks, Kay --IS0zKkzwUGydFO0o Content-Type: text/plain; charset=us-ascii Content-Disposition: inline; filename="udev.8" .TH UDEV 8 "October 2003" "" "Linux Administrator's Manual" .SH NAME udev \- Linux configurable dynamic device naming support .SH SYNOPSIS .B udev .SH "DESCRIPTION" .B udev creates or removes device node files usually located in the /dev directory. As part of the .B hotplug subsystem, .B udev is exectuted if a kernel device is added or removed from the system. .P On device creation, .B udev reads the sysfs directory of the given device, to collect device attributes like label, serial number or bus device number. These attributes are passed as a key to the namedev subsystem to receive a unique name for device file creation. namedev maintains a database for devices present on the system. .P On device removal, .B udev queries the namedev database for the name of the device file to delete. .P namedev expects its configuration at .I /etc/udev/namedev.config. The file consists of a set of lines. All empty lines and lines beginning with a '#' will be ignored. .br Every line defines the mapping between device attributes and the name of the device file.
