Hi List, first of all thanks for your response. I was able to solve the problem on my own now, but i think it's worth mentioning what the problem was. First of all ks installation is different (or has other/more bugs/features) in RH6.0/6.1/6.2 My problem was that i specified a disk partition which caused anaconda to silently bail out (without errors or warnings. Not even in the <ALT>-F2-F5 screens! (mkkickstart also fails!!!) When i installed the machine for the first time i did a manual disk layout and recorded the partition size/locaten and re-used this in the automatic installation. THIS WAS THE FAULT! I recogniced, that disc druid (during interactive installation) allocates (or tries to allocate) more space for a partition (depending on the cylinder boundary???).This is also true for the automated kickstart installation (whatever is used to do the partitioning ...) E.g. telling disk druid to make /boot 16MB resulted in a 23MB partition ... So here is my solution: clearpart --linux part /boot --size 16 part / --size 6666 ---> max. size of the / partition and this causes the error. reserve some space (e.g. 8-16MB) and make this partition (or others) only 6658MB large, then disc druid (or whatever is used during anaconda installation) has some 'room' to allocate on correct cylinder boundaries. The kickstart install will *silently* fail if your disc layout is 'incorrect'. The interactive installation using fdisk or disc druid will warn you in this case, and you can correct this problem, but kickstart simply bails out. part /var --size 1024 part /tmp --size 512 part swap --size 512 install I hope Red Hat will provide better ks installation features in the future! best regards Thomas P.S.: Has anybody found an elegant way to merge updates *.rpm (e.g. also new kernel updates) to an existing CD-ROM installation image. So the installed machine will get updated automatically. I hacked/modified the perl script printed in the Kickstart-HowTo, but it's not perfect (currently i have not enough time ...) -- Thomas Mandl System, Network & Security Admin phone: +43 1 877 56 45/53 Thomas NEUROTH Ges.m.b.H. fax: +43 1 876 49 20 Hietzinger Hauptstrasse 22 e-mail: Thomas.Mandl@xxxxxxxxxxxxx A-1130 Vienna/Austria NIC-HDL: TM4373, TM539-RIPE
