Linux内核错误 修复
环境介绍：Centos5.2+2.6.18-8.el5内核，编译器是GCC4.1.2。
要编译的内核2.6.18-8.el3
仅仅修改了部分内核的配置信息，没有大的变化。
然后：make ;make modules;make modules_install;
编译没有出问题，生成了内核，mkinitrd生成了initrd，加到lilo.conf中，重启选择新内核，出现一下问题：
hub 3-0:1.0: USB hub found
hub 3-0:1.0: 2 ports detected
Scanning and configuring dmraid supported devices
Trying to resume from LABEL=SWAP-hdc4
No suspend signature on swap, not resuming.

no fstab.sys, mounting internal defaults

setuproot: error mounting /sys: No such file or directory
Switching to new root and running init.
unmounting old /dev
unmounting old /proc
unmounting old /sys
switchroot: mount failed: No such file or directory
两者区别就是编译器版本一个是gcc3.4，一个是gcc4.1，后者编译通过，但是不能引导系统。
解决方法：
Here's the fix
After almost giving up on Fedora 5, I finally got the fix to this problem.
The
suspend signature on swap error, "Trying to resume from
LABEL=SWAP-hdd3. No suspend signature on swap, not resuming", can be
ignored. It gives this error because when the volumes are activated
(look at the output previous to this error), it resumes the swap
partition in that step. Therefore, it's trying to resume something that
isn't suspended.
The error that causes all the trouble is
"mount: could not find filesystem '/dev/root'". Appartently, in the
init script within initrd-2.6.15-1.2054_FC5.img, the command 'mount
/sysroot' is trying to mount /dev/root to /sysroot. Fedora 5 does not
use /dev/root like in the previous versions of Fedora. Instead, it uses
'/dev/VolGroup00/LogVol00' or '/dev/hda1' (or wh

linux命令是在bash环境下运行，最常用的Shell和命令下面做下总结
1.ls 显示当前目录下的文件和目录
通常搭配参数L ，完整显示文件和目录，权限，时间、归属
搭配A，显示 “.” 的目录和文件
2. cat 查看文件内容
通常搭配重定向符号> ，> 是把一个文件的内容加载到另外一个文件内容里去 例： cat 1.tx ......
