   4 Subject: [PATCH] fastboot: fix issues and improve output of bootgraph.pl
   5
   6 David Sanders reported some issues with bootgraph.pl's display
   7 of his sytems bootup; this commit fixes these by scaling the graph
   8 not from 0 - end time but from the first initcall to the end time;
   9 the minimum display size etc also now need to scale with this, as does
  10 the axis display.
