[CentOS] LVM and kickstarts ?

[Michael Gale]

Hey,

	So I have created another kickstart that I believe should be correct 
and it fails the same way with the same problems:

--snip--
zerombr yes
clearpart --all --initlabel
part /boot --fstype ext3 --size=100
part swap --size=1000
part pv.os --size=8000 --grow --maxsize=8000 --asprimary
volgroup os_volgroup01 pv.os
logvol / --fstype ext3 --name=os_root --vgname=os_volgroup01 --size=1024 
--grow
--snip--
