    I have a server that I ran the wrong command on: mv /* /enter/some/directory/here/ This resulted in moving a number of my system files into the "here" directory. The server will no longer allow me to login via ftp or via root because it moved some of system files... I can boot into rescue mode, but not sure that will help. I'm looking for someone that can fix this issue on this one server, it's a debian 8, reformatting the disk is not an option.
