Try modifying the snippet to have the while inside a subshell:
Original:
# Loop until the corresponding rpm is installed
if [ "$keys_found" = "yes" ]; then
while : ; do
sleep 10
...
done &
fi
Use subshell:
# Loop until the corresponding rpm is installed
if [ "$keys_found" = "yes" ]; then
(
while : ; do
sleep 10
...
done
) &
fi
I have found other times that some versions of bash do not parse properly with
& on the line. The version of bash you are using is a function of what is
supplied on the target system _and_ it is what's on the minimal install
environment which may not keep up with fixes.

No ... it doesn't help. :-(
In the main screen i see "Running pre-installation scripts" and nothing happen
anymore.
Via ps i can see, the script is still running.
I put "exit" one time in the snippet and the other time in the %pre section.

Yes ... the install process stops, so the script is not in the background.
I can see it, when i use terminal access via ALT F2 etc.
You mean something like this?:
%pre
$SNIPPET('keep_ssh_host_keys')
exit
%end

Are you sure its not backgrounding?
I've not pinned down the exact cause, but I've had a similar problem in the
past. I found that an explicit `exit` at the end of %pre solved my problem.

Hi all again,
ok, first point was my fault: Upgrading cobbler on this cobbler host to the
current
version helps. :-)
But the second problem still exists:
The bash script is not able to put a "while" construction in background, so the
script is stilling waiting at this point. It looks, like the job control is not
working at this moment (when i use one terminal of this client system to
install and i test
it there, job control is working ... while the %pre-script is still in
foreground.).
So, what is still wrong?
Is there a kernel option or an anaconda option to control this behaviour?
Thanx for any help.

Hi all,
i am testing the snippet keep_ssh_host_keys.
Well, i am a beginner in cobbler and maybe my problem is a bash problem, but
when i use keep_ssh_host_keys i have two problems:
When i use keep_ssh_host_keys as snippet, i see while kickstart is running:
Unknown command: <!DOCTYPE
Why?
Well, than i put the whole keep_ssh_host_keys script in my kickstart file
and now the script is running until the last part (i can see, the keys are
saved in /tmp):
# Loop until the corresponding rpm is installed
if [ "$keys_found" = "yes" ]; then
while : ; do
sleep 10
if [ -d /mnt/sysimage$SEARCHDIR ] ; then
cp -af /tmp/$TEMPDIR/${PATTERN}* /mnt/sysimage$SEARCHDIR
logger "keys copied to newly installed system"
break
fi
done &
fi
The kickstart process stopped and i think the loop is running, but not
in the background, so the installation process cannot proceed.
Why?
Thanx for any help!
