蛋疼的can't run '/etc/init.d/rcS': No such file or directory
内核启动出现这样的错误：can't run '/etc/init.d/rcS': No such file or directory；简单的启动信息如下：
rtc-pcf8563 0-0051: low voltage detected, date/time is not reliable.
rtc-pcf8563 0-0051: retrieved date/time is not valid.
rtc-pcf8563 0-0051: hctosys: invalid date/time

Processing /etc/profile... Set search library path in /etc/profile
Set user path in /etc/profile
Set PS1 in /etc/profile
Done

[root@/]#
这个rcS的权限已经设置为777了，rcS文件也没有乱码，其内容如下：

#! /bin/sh
echo "----------mount all"
/bin/mount -a


echo "----------Starting mdev......"
/bin/echo /sbin/mdev > /proc/sys/kernel/hotplug
mdev -s

mount -t yaffs /dev/mtdblock6 /usr

syslogd -O /usr/PGS/log/messages -s 2 -l 7


在同一个内核下，烧写以前的根文件系统却没有问题，能正常启动rcS,他的启动信息如下：
rtc-pcf8563 0-0051: low voltage detected, date/time is not reliable.
rtc-pcf8563 0-0051: retrieved date/time is not valid.

求高手指点迷津，这问题已经搞了1个星期了，毫无思绪~~~~


------解决方案--------------------
can't run '/etc/init.d/rcS': No such file or directory确认这个rcs有没有，再把权限改为544试试。
------解决方案--------------------
明显没有此文件。
启动后，ls /etc/init.d/rcS看看。
------解决方案--------------------
/etc/init.d/rcS 有没可能你这是个链接文件。
