9、用rootdev变量来决定可选root设备。利用set variable=value来替换缺省内核参数。注意：1、修改内核参数前最好做备份。2、修改内核参数后，需要重新启动系统。例如可以用forceload命令强制载入一些系统moduleforceload: drv/foo也可以设置一些系统变量例如pt_cnt定义可配置的pseudo-ttys (default is 48)的数目(系统的内核参数)，如用户可以打开的最大文件句柄数。set pt_cnt=100set npty=100set sadcnt=200set nautopush=100b）设置模块变量#vi /etc/system s
10、et module_name:variable=value1、备份原/etc/system文件。#cp /etc/system /etc/system.gen2、修改/etc/system文件，增加内核变量。Set maxusers=483、重新引导系统。注意：修改此文件时必须小心，因为它改变了内核的操作maxusers内核变量确定系统上最多用户个数。 默认情况下，该值近似为系统物理内存的Mbyts数，我们可以根据 需要重新设置，以反映一个系统的实际负载。但maxusers的值不应 设置得太高，系统允许的最大值为2048，可以通过修改/etc/system 实现。下面有有一个实例：它参照set
