Try this in your kickstart file:

%post --interpreter /bin/bash yes | yum update

Without the '--interpreter /bin/bash' the code will (I think) be interpreted as python. Also, when you run 'yum update' you are prompted to confirm that you want to go ahead and update the listed packages, and so you need to pipe 'yes' through it.

thanks for the response - with regard piping yes through to yum it seems you can just specify yum -y update and this will anser yes for you.

the interpreter bit is now causing the end of the kickstart to bomb out with the error of '/usr/local/bin/bash can not be run' as this is where bash is it seems. This is the %post bit of the kickstart

%post --nochroot --interpreter /usr/local/bin/bash /usr/bin/yum -y update

Firstly, try it without the --nochroot as this switch makes the code run in the install system environment rather than chrooting into the newly installed system. Even if the commands worked, packages would be installed into the temporary file system in memory rather than onto disk. Secondly, it shouldn't be /usr/local/bin/bash unless you have installed a custom bash package. However, you should be able to use '--interpreter /bin/sh' to use the Borne shell instead of bash.

Does the -y switch also answer yes to importing the GPG key? If not, you will need to import the key prior to running yum.

you need to run this without the --nochroot option, there is no yum included in the installer system, and the only yum you will get working is the one inside the chroot.

also, what made you install bash in /usr/local/bin ????

OK thanks makes sense - however is there anyway to make some things run with --nochroot and others with it? Just that there is other things allready going on that need the --nochroot

First thing that comes to mind is:

%post --nochroot # Some non-chroot stuff

chroot /mnt/sysimage

# All the chrooted stuff here

yum -y update

...

i didn't - taken over systems and when i check a system that is allready kickstarted it says that bash is in /usr/local/bin

I would investigate that. It seems, well, less than intelligent in an RPM-based system.

You can have both:

%post --nochroot <Some stuff>

%post --interpreter /bin/sh <More stuff>

This is what the end of my kickstart file looks like:

%post --nochroot --interpreter /bin/sh cp /tmp/hostname /mnt/sysimage/root/.

%post --interpreter /bin/bash mount 192.168.100.1:/exports/centos /mnt cd /mnt ./scripts/post_install.sh

Hijack the firstboot mechanism.

how would one do that??

I do our installs via PXE / HTTP, I go and get a post install script and run it. This way I don't have to muck around with the php scripts that generate the kickstart files for the installs.

%post mkdir -p /root/bin; cd /root/bin wget -q http://centos-4-repo1.XXX.XXX/yam/centos4-i386/install/post-install.sh sh /root/bin/post-install.sh 2>&1 | tee >> /root/post-install.log

Script on the kickstart server - post-install.sh

rm -rf /etc/yum/repos.d/*

cat >> /etc/yum.conf << "EOF" [base] name=CentOS-$releasever - Base baseurl=http://centos-4-repo1.XXX.XXX/yam/centos4-i386/RPMS.os http://centos-4-repo2.XXX.XXX/yam/centos4-i386/RPMS.os gpgcheck=0

yum -y update
