Create the file when the file does not exist

I realized Lumberjack in the audit module of Kubernetes.

When the file is deleted, it needs to be recreated without restarting the process to ensure that the log is not lost.

I don't really want to incur the overhead of doing an os.stat on every single write.

A better way to do this is to handle the error when you try to write to a file that's been deleted. They way the only overhead is when the file is actually missing.

This sounds correct.
I noticed that many log libraries do not have this kind of log file loss judgment. Can you share your opinion on this?
For the time being I only think of goroutine, not sure if lumberjack is needed.
