I need to spend some time and fix it. That "No such file or directory" is from the way trace-cmd does error handling. It checks if errno is set and if so, it prints out perror(). What usually happens is I do a stat() on a file which sets errno, and forget about it. Then if trace-cmd finds some internal error, it calls the warning() message, which then prints out the stale errno.
