启动时Mounting local filesystems... 最后显示failed.（根分区设置成只读）

[higeon <higeon@gmail.com>]

根分区设置成只读后启动时Mounting local filesystems... 最后显示failed.

系统是Debian 5.04 lenny
按照下面的链接文章我把根分区设置成只读。
http://wiki.debian.org/ReadonlyRoot

在没有改根分区为只读之前一切正常。

把根分区改成只读，重新启动的时候发现
在Mounting local filesystems...的最后，显示一个failed。
但是启动能正常进行，系统也可以正常登录。
看不出哪里有什么问题。

到底是什么东西失败才报出这个failed？

下面是启动画面显示信息：
