Hi Ryan,

   Thanks for this; I confess to not having looked in bugzilla and have 
just done so (more below).

   I was able to do a pseudo-hands-off install by specifying everything 
in a ks.cfg file *except* partitioning information, which of course 
dropped anaconda out to prompt for partitioning information.  All the 
existing partitions were detected, both native and LVM and I dutifully 
edited each in turn, adding the mountpoints and specifying whether or 
not to reformat.  Kickstart then proceeded and installed as I wanted. 
This approach may help other correspondents wishing to upgrade no more 
than a few machines.

   Having installed as described above I looked with anticipation at 
"/root/anaconda-ks.cfg" to see what I *should* have done.  The 
partitioning detail is here.  It remains to be seen whether this works. 
  I will test it and report back.  I note the absence of "--useexisting" 
as per bug 189123.

# The following is the partition information you requested
# Note that any partitions you deleted are not expressed
# here so unless you clear all partitions first, this is
# not guaranteed to work
#part /boot --fstype ext3 --onpart sda1
#part pv.4 --noformat --onpart sdc1
#part pv.3 --noformat --onpart sdb1
#part pv.2 --noformat --onpart sda2
#volgroup vg00 --pesize=32768 pv.2 pv.3 pv.4
#logvol /vol0 --noformat --fstype ext3 --name=lvol0 --vgname=vg00 
--size=161440
#logvol /vol1 --noformat --fstype ext3 --name=lvol1 --vgname=vg00 
--size=161440
#logvol /tmp --fstype ext3 --name=ltmp --vgname=vg00 --size=50016
#logvol swap --fstype swap --name=lswap --vgname=vg00 --size=32768
#logvol / --fstype ext3 --name=lroot --vgname=vg00 --size=9024

   Bug 150206 (opened on 3rd March 2005 and apparently untouched since!) 
more closely matches my issue
