Because they all depend on libc.so. You could also happen to above boring stuffs when you remove some key files in Linux OS. Now, I have a good idea to solve above problems. We could implement a File System to record all the operations which send to VFS. Then when you think you have done a mistake command, you could rollback from this File System. This is just a RFC, I would give detail implementations. Would anyone please give me some suggestions?
