Better handling of files in tmpfs /var/log

Hi @borpin,

I can definitely fix this on my own box now that I have SSH access, but that’s not my point. I think it creates a very bad user experience if most of the emonPis out there are crashing randomly and it’s just written off as a known problem without a solution. So I wanted to fix it for everyone, not just for me.

Log2ram seems controversial so I would not propose a solution that incorporates it right now. I’d favour simple changes to our default configurations to improve matters for everyone. It may make no difference to those who have already installed log2ram, but I’d guess they are the minority.

Thanks, Chris.
