别人的硬件跟你不尽相同，不一定有用
想去掉 initd，重点是要确保内核启动时能辨认根分区的文件系统格式然後加载根分区，所以相关的支援要直接编入内核，不要编成模块
其次是硬件支援，这关乎 SATA、SCSI、IDE 之类的，有了这些，基本上行矣
我的lsmod显示是没有模块的，如下，说明我已经把说有的东东都编译进内核了，问题是我的还是产生了个比内核（可用）小的多的initrd.img.我的主板是intel845的。硬盘是ide的，我用lshw看的，问题是有几个个scsi选项显示(－*－`)被其他设备依赖了，其中有一个模块的参数自动默认为m（CONFIG_SCSI_WAIT_SCAN=m），不能改成＝y,很晕人。我看了它的help也是一头雾水。
其中一个help:
If you wish to export transport-specific information about │
│ each attached FiberChannel device to sysfs, say Y. │
