Hopefully this example will help. You should be able to configure your
hostname logic like the following:
We had to do the following with CentOS 7.2 and Oracle Linux 7.2, because
there is a bug with how the static --network line is being generated. (Bug
opened with support and they have confirmed).
Systems -> Kickstarts -> Profiles -> {profile} -> Kickstart Details ->
Advanced Options -> Custom Options:
%include /tmp/network.out
Systems -> Kickstarts -> Profiles -> {profile} -> Scripts:
Name: Static_BUG
$SNIPPET('spacewalk/1/72network_bug')
Pre-Script
Check template --> Do not forget this, or it will not work.
%pre --log /tmp/ks-pre.log.1
# BEGIN: network Snippet
# Issue with CentOS 7.2, not able to handle just network --bootproto

cat /proc/cmdline > /tmp/cmdline.out
server_ip=`awk -F"ip=" '{print $2}' /tmp/cmdline.out |awk '{print $1}'|awk

server_gw=`awk -F"ip=" '{print $2}' /tmp/cmdline.out |awk '{print $1}'|awk

if [[ -n "$server_host" ]]; then
cat <<_EOF >/tmp/network.out
network --noipv6 --onboot=yes --bootproto static --ip=$server_ip
--netmask=$server_nm --gateway=$server_gw --nameserver=$server_dns

# Another snippet will handle hostname, /etc/hostname, /etc/hosts,

else
cat <<_EOF >/tmp/network.out
network --noipv6 --onboot=yes --bootproto static --ip=$server_ip

# END: network Snippet
- Thanks and good luck

After installation there's no file pre_install_network_config in tmp
directory..
May be nochroot can help?

Are you including that file?
The following will need to be in your kickstart...
%include /tmp/pre_install_network_config

Stuck on this problem - I wanted to set up hostname for KVM machine on
pre,
ok - I spent 3 days, but in fact ks ignore all pre sections...
also I found that Spacewalk trying to set hostname by itself, here the
text from anakonda.cfg
# Start of code to match cobbler system interfaces to physical interfaces
by their mac addresses
# Start eth0
# Configuring eth0 (00:16:3e:53:0e:0d)
if mac_exists 00:16:3e:53:0e:0d
then
get_ifname 00:16:3e:53:0e:0d
echo "network --device=$IFNAME --bootproto=dhcp --hostname=virttest001"
>> /tmp/pre_install_network_config
fi
But no logs, no errors, no other stuff. Also no my pre scripts in /tmp
directory
Any thoughts?
