Modify

Vi/usr/src/linux-2.6.35.4/.config

Change #config_sysfs_deprecated_v2 is not set to Config_sysfs_deprecated_v2=y because the old version of MKINITRD and its Nash are not config_sysfs_ in the kernel The DEPRECATED_V2 parameter uses the old version of the SYSFS path format by default, so that the hard disk information node within the/sys is not properly accessed under the new kernel, and if you do not modify the kernel, you will not be able to find any errors such as VolGroup00, and the kernel boot fails directly. File system mount error.

Copy the original file to overwrite the. config file in the directory
