NAME
kudzu - detects and configures new and/or changed hardware on a systemSYNOPSIS
kudzuDESCRIPTION
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 hard-
ware, 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/modules.conf,
/etc/sysconfig/network-scripts/, and /etc/X11/XF86Config.
以下是这个命令执行的输出示例：
