Redhat RHN (re)-joining in Kickstart

Thu Mar 30 14:58:51 UTC 2006

Thanks for the help guys.

It seems the final solution looks a little something like this....

HOSTNAME=`grep $IP /kickstart/hosts | awk '{print $3}'`
IP=`ifconfig eth0 | grep inet | awk '{print $2}' | awk -F: '{print $2}'`
HOST=`grep $IP /kickstart/hosts | awk '{print $2}'`
echo "$IP       $HOST   $HOSTNAME" >> /etc/hosts
hostname -v -- "$HOSTNAME"

/kickstart is a directory previously mounted from the NFS server, where 
I have a "host" file, that is a file that is laid out like a hostfile 
(ish), with no comments in. eg

(sample line)
192.168.0.1	mymachine	mymachine.mynetwork.co.uk	10.0.0.1

The last IP address allows me to place the machine on two different 
networks.

Here's the kickstart Stuff

echo "Registring with RHN"

/usr/sbin/rhnreg_ks --activationkey=<insertl long key here>
echo " "
echo "Running up2date"
/usr/sbin/up2date up2date
/usr/sbin/up2date -u

The reason for using an activation key means that they go back into the 
right group at the end of the kickstart (that bit was the important 
bit). the reason for not wanting to use --profile is that that implies 
that there is a profile there already (in our case there might not be)

You may notice that I first up2date up2date, before updating the system, 
that's because in the version of RHAS3 (rh3 no updates) I'm 
kickstarting, it has problems with dependencies on the x64_86 architecture.

I also don't up2date the kernel here because of various (other) system 
dependencies that break on a kernel upgrade without 
modification/recompile/reinstall.  This ensure that the system comes up 
working, and as secure as possible to ensure that we can get working 
straight away.

Admitedly I don't need all this detail here, but it's here for those 
that happen to google this problem in the future.

Thanks for the help solving this problem
