I have detailed notes about setting up the Spacewalk organization, populating
the channels, creating groups & activation keys up to the kickstart
profile. I believe the key for reproducing, however, is to just use this for
your Partition Details:
  part /boot --fstype=ext3 --size=200 
  part pv.01 --size=1000 --grow 
  part swap --size=8192
  volgroup myvg pv.01 
  logvol / --vgname=myvg --name=LVROOT --size=30720
  logvol /opt/data --vgname=myvg --name=LVOPTDATA --size 64 --grow

If you'd still like further details, then I'd happy to share. 

Thanks,
