Well
i have begin to learn python to solve my problem.
Here is what i have done
As i m a total beginner in python i m sure there s a lot of
improvement which are possible.
Moreover there s a lot of assumption that have been made
-only ide disk
-only one disk
-no /var partition.
Thanks for all people that have answered to my question
in the kickstart file i have
%post --nochroot
chvt 3
(
mv -f /tmp/tempo/ssh_host_* /mnt/sysimage/etc/ssh
mv -f /tmp/tempo/local* /mnt/sysimage/var/cfengine/ppkeys
)
%pre --interpreter /usr/bin/python
import urllib, os
partition_script="/tmp/backupkey.py"
if not os.path.exists(partition_script):
url="ftp://crotale.int-evry.fr/pub/ks/backupkey.py";
urllib.urlretrieve(url, partition_script)
os.system('chmod 755 ' + partition_script)
os.system(partition_script)
And here is my backupkey.py script
#!/usr/bin/python
