I'd like to be able to make the *scratch* buffer persist between sessions.

I realise that it is meant for things I don't want to save.  But every few months, I get interrupted or distracted, and realise I have quit emacs or rebooted a machine while there was something significant in *scratch*.  To know that I wouldn't lose stuff when that happened, I'd happily pay the price of having to flush the buffer occasionally.

I can't be the only one that is bitten by this from time to time.
