Re: [patch] [4.0.0alpha2] Pool graphs

Alexander,

Thanks for the patch.  I've included this in 4.0.0, and it will be in the
next alpha3 version, which hopefully I will release next weekend.

I implemented it slightly differently, including moving all the rrd code to
a new utility that BackupPC executes daily (after BackupPC_nightly) in the
background (to avoid blocking by doing a system()), but it is largely based
on your code.  It also generates and saves the graphs, rather than creating
them on-the-fly.

I also changed the existing status reporting to use GiB (2^30) and MiB
(2^20) to match the numbers in the graphs.

Craig
