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!

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.

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.

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

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.

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.

Well, it doesn't work ....
B.t.w. my client system to install is Fedora 16.
The while-loop is looking for the directory /mnt/sysimage/etc/ssh.
When i create it at this phase via cmd line the script does the rest
and everything is going on.
But the script is called by /bin/sh. Of course this is a link to /bin/bash, but
maybe this is the problem????? Other scripts later are running with /bin/bash.
