The kickstart is intended to create images which can also run on real iron, including those with "real" storage ( brocade, qlogic etc ). Therefore the firmware is left there on purpose. As of removing the firmware in %post: yes, it is one way to do it. But I find it awkward to install something just to remove it seconds later. As of ks file size: who cares ? You create it once and use it as many times as needed. An extra dozen or hundreds of bytes / couple of lines are not significant in this context And last but not least: You can always tweak the ks to fit your specific needs. This one is meant for an _almost_ minimal but yet general context. If you really want to go "minimal" there are at least other 5 packages that can be removed ( but this will, of course, remove some of the functionality , such as processing delta updates or selinux ). If you want to go this road, even yum itself can be removed. _______________________________________________ CentOS-virt mailing list CentOS-virt@xxxxxxxxxx http://lists.centos.org/mailman/listinfo/centos-virt
