# This is a basic Fedora 21 spin designed to work in OpenStack and other # private cloud environments. It's configured with cloud-init so it will # take advantage of ec2-compatible metadata services for provisioning ssh # keys. Cloud-init creates a user account named "fedora" with passwordless # sudo access. The root password is empty and locked by default. # # Note that unlike the standard F20 install, this image has /tmp on disk # rather than in tmpfs, since memory is usually at a premium. # # This kickstart file is designed to be used with appliance-creator and # may need slight modification for use with actual anaconda or other tools. # We intend to target anaconda-in-a-vm style image building for F20. text lang en_US.UTF-8 keyboard us timezone --utc Etc/UTC auth --useshadow --enablemd5 selinux --enforcing rootpw --lock --iscrypted locked user --name=none firewall --disabled bootloader --timeout=1 --append="no_timer_check console=tty1 console=ttyS0,115200n8" --extlinux network --bootproto=dhcp --device=link --activate --onboot=on services --enabled=network,sshd,rsyslog,cloud-init,cloud-init-local,cloud-config,cloud-final zerombr clearpart --all part / --size 3000 --fstype ext4 %include fedora-repo.ks reboot # Package list. %packages --instLangs=en kernel-core @^cloud-server-environment # rescue mode generally isn't useful in the cloud context -dracut-config-rescue # Some things from @core we can do without in a minimal install -biosdevname -plymouth -NetworkManager -iprutils -kbd -uboot-tools -kernel -grub2 %end %post --erroronfail # Create grub.conf for EC2.
