Did we already report a bug to get the better bootchart into Debian, I 
don't seem to find it?

The readahead in Debian seems to be quite old, Raphael Geissert tried 
the one from RedHat which seems to be better, maybe we should consider 
having readahead upgraded or use the improved sreadahead that could work 
beside sdd?

What will we do about the large initrds (because of the difference 
between 'most' and 'dep') and about the large duplication of things run 
in initrd as well as afterwards?
