Uh, ok. I didn't notice that.

I like this version. The only comment is that first and last chapters both 
tell how the recovery works if this option is chosen. This version doesn't 
tell what the situation is if this option is not chosen. Therefore I would 
either keep the last chapter intact or combine the last chapters of old and 

Another thing, which doesn't really concern the template, is that run during 
system boot probably doesn't help very many people (I would think). It helps 
if Nethack crashed because the playing server booted, but in other situations 
that recovery would be too late. If my connection drops I would like to 
continue playing as soon as I get the connection up, not when the server is 
booted for kernel upgrade five months later. :-)
