kudzu - detects and configures new and/or changed hardware on a system
kudzu detects and configures new and/or changed hardware on a system. When started, kudzu detects the current hardware, and checks it against a database stored in /etc/sysconfig/hwconf, if one exists. It then determines if any hardware has been added or removed from the system. If so, it gives the users the opportunity to configure any added hardware, and unconfigure any removed hardware. It then updates the database in /etc/sysconfig/hwconf.
If no previous database exists, kudzu attempts to determine what devices have already been configured, by looking at /etc/modprobe.conf, /etc/sysconfig/network-scripts/, and /etc/X11/xorg.conf.
--usage Show short usage message. --help, -? Print help information. -q, --quiet Run quietly; do only configuration that doesnt require user input. -s, --safe Do only safe probes that wont disturb hardware. Currently, this disables the serial probe, the DDC monitor probe, and the PS/2 probe. -t, --timeout [seconds] This sets the timeout for the initial dialog. If no key is pressed before the timeout elapses, kudzu exits, and /etc/sysconfig/hwconf is not updated. -k, --kernel [version] When determining whether a module exists, use the specified kernel version. (If this is not set, it defaults to the current kernel version.) Do not specify suffixes such as smp or summit; these are automatically searched. -b, --bus [bus] Only probe on the specified bus. -c, --class [class] Only probe for the specified class. -f, --file [file] Read hardware probe info from file file and do not do an actual probe. -p, --probe Print probe information to the screen, and do not actually configure or unconfigure any devices.
/etc/sysconfig/hwconf Listing of current installed hardware. /etc/sysconfig/kudzu Configuration for the boot-time hardware probe. Set SAFE to something other than no to force only safe probes. /etc/modprobe.conf Module configuration file. /etc/sysconfig/network-scripts/ifcfg-* Network interface configuration files.
The serial probe will disturb any currently in-use devices, and returns odd results if used on machines acting as serial consoles. On some older graphics cards, the DDC probe can do strange things.
Running kudzu to configure network adapters post-boot after the network has started may have unintended results.
