Subject Re: Understanding Bootstrapping
Date Thu, 25 Feb 2010 04:26:23 GMT
Bootstrap files are streamed directly to data locations as .tmp files
and renamed when complete.

One of the problems w/ 0.5's bootstrap is indeed that it doesn't give
you any visibility into what is going on.  This is addressed in 0.6 w/
additional JMX reporting.
