Linuxx-server crashed

Linuxx-server crashed-Linux general technology-Linux technology and application information. The following is a detailed description. Some time ago, I debugged the java output graph and destroyed some underlying class library rpm packages of x-server. Today, I opened a computer and cannot access the xwindow interface, after finding the boot disk to restore the linux rescue, we found that the chroot, mnt, and sysimage commands did not function, then, manually mount the broken system to/mnt and mount-t ext3/dev/sda7/mnt. How can I not mount several zones, fortunately, all the data is backed up on the partitions that can be mounted. It seems that the data can only be reinstalled. The original system was Federo8, and this time we plan to install 9. Linux rescue recovery has always been a good way to rescue the system. Generally, you can use the command chroot to mount it to the system to be restored. If this command is invalid, you only need to manually mount the broken system.
