[Spacewalk-list] Kickstart Profiles and Naming (Francisco Manuel Cardoso)

[Corey Hemminger]

I have scripts in my kickstart profile that allows me to customize the server and it registers with spacewalk with the correct name then. This works with text install and uses the current terminal anaconda is using. Haven't tested with GUI install. 

Allows config of hostname, network bonding, and can be expanded for any other configuration variables needed. Simply asks all inputs at the beginning and transfers variables into chroot environment to be used by post install scripts to finsh configuring the server. Not the prettiest script but it works.

Make sure to add "%include /tmp/network" without quotes to Kickstart > profile> advanced options tab > Custom Options.

Hello,

 

After a bit of a rough patch implementing and getting used to the new 2 "interface" im left with a question.

When kickstating machines it seems to be possible to make them register to spacewalk on "boot", is there a way I can assign a pool of hostnames to the profiles so that they come out named and "in order" ?

 

Cheers

 

Francisco
