KickStart PostInstall

[K.C. Chan]

All,
I want to install updates rpm after installing RH Linux via kickstart. How would I mount this and run the rpm installs command during postinstalls (How would I enter this command in the postinstalls section?). I want to also untar my apps as well. Thanks.

How are you doing the install? via NFS?

If so, you'll just be able to mount your NFS path using standard mount commands, and then 'rpm -Fvh /path/to/eratta/*.rpm'.

Same goes for the files you wish to un-tar.

The commands are entered into a %post section of the kick-start configuration, and are exected in a chroot environment of the destination volume.

If you dig up the RedHat Customisation guide, it has a section on KickStart which goes over all of this (i.e. http://www.redhat.com/docs/manuals/linux/RHL-8.0-Manual/custom-guide/s1-kickstart2-postinstallconfig.html)

I've been working on a similar issue for updating the kernel as a post install kickstart option utilizing RPMs. I'm still burning the modified install CD (RedHat Linux 6.2), so I'm T-20 minutes from actually testing this out. Here is some %post install gibberish that might help you out:

#Do this first before %post
%post --nochroot

#Create a directory on the newly created
#system image for your RPMs (on cd)
mkdir /mnt/sysimage/myRPMs

#Copy RPMs from your CD to the system image
cp /mnt/source/myRPMs_on_CD/*.rpm /mnt/sysimage/myRPMs

%post

#Finally, install the RPMs
rpm -ivh /myRPMs/*.rpm

Again, I haven't had the chance to test this out yet, but I hope it helps. More to come...
