Dober dan, Ziga and others :-)
As far as I can tell, the specfile in latest SVN only builds one RPM, containing both bootchart and bootchartd.
It would be really good if there were two RPM packages: one containing bootchartd alone, which would not depend on Java etc, and the other containing bootchart, with its heavier Java dependencies.
This would make it much easier to install bootchartd on one machine, and use it to gather boot stats there, then copy the .tgz to another machine with Java installed, and generate the graphs there.
As far as I can tell, in the current source code, there is already a nice clean separation between the information gathering and the graph generation components. So that existing separation just needs to be reflected in the packages.
The Debian project similarly ship just one package 'bootchart', containing both bootchart and bootchartd.
