How much of the manual needs adjustment for 9.0?

[james]

I originally installed without selecting sources.

The manual says to run sysinstall and do the configuration step to add 
source distribution and I did that, but it then failed to download the 
'sbase' source.  I admit I gave up 'fairly quickly' and just downloaded 
src.txz, but its not clear to me how many of the functions of sysinstall 
are still supposed to work with a 9.0 release.
