下面我们要修改/test/a/modules下的：pci.ids modules.alias modules.info
[root@localhost modules]# vi cpi.ids
[root@localhost modules]#vi modules.alias
在上述文件中加入rh5.2img中cpi.ids和modules.alias modinfo中的内容追加在后面
[root@localhost modules]# ls
2.6.18-194.el5 module-info modules.alias modules.cgz modules.dep pci.ids
[root@localhost modules]# rm -rf modules.cgz
[root@localhost modules]# find 2.6.18-194.el5/ |cpio -H newc -ov |gzip -9 -c - > modules.cgz
