Hi all,
Recently, I just do some stupid stuffs as follows.
# mv /lib/x86_64-linux-gnu/libc.so.6 /tmp
After move "/lib/x86_64-linux-gnu/libc.so.6" away, you could not run lots of commands, which show you some errors like this.
# ls ls: error while loading shared libraries: libc.so.6: cannot open shared object file: No such file or directory # mv mv: error while loading shared libraries: libc.so.6: cannot open shared object file: No such file or directory ...
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? Thanks very much.
