如何在 Cobbler 上导入和启动 Ubuntu
Cobbler 在 CentOS/RHEL/Fedora 系的发行版上工作良好，在 CentOS/RHEL/Fedora 上安装 Cobbler 以后可以直接导入 CentOS/RHEL/Fedora ISO 文件，很顺利，不过导入 Ubuntu/Debian ISO 就不是那么幸运了，直接导入 ubuntu-11.10-server-amd64.iso 的话会报错：# cobbler import –path=/mnt/ –name=ubuntu-11.10-server-amd64

忽略上面的错误，会发现在 ks_mirror 下面已经导入了 ubuntu-11.10-server-amd64 整个 ubuntu 目录：
# ls /var/www/cobbler/ks_mirror/
configubuntu-11.10-server-amd64
如果对上面已经导入的 ubuntu 目录还不放心的话，可以删除这个目录后手动导入（直接 cp 就行）：
# rm -rf /var/www/cobbler/ks_mirror/ubuntu-11.10-server-amd64
# mount -o loop -t iso9660 ubuntu-11.10-server-amd64.iso /mnt
# cp -r /mnt/ /var/www/cobbler/ks_mirror/ubuntu-11.10-server-amd64
完成导入（拷贝）后，做个链接：
# cd /var/www/cobbler/links/
# ln -s /var/www/cobbler/ks_mirror/ubuntu-11.10-server-amd64 ubuntu-11.10-server-amd64
然后加入 distro 和 profile：
# cobbler distro add --name=ubuntu-11.10-server-amd64 --kernel=/var/www/cobbler/ks_mirror/ubuntu-11.10-server-amd64/install/netboot/ubuntu-installer/amd64/linux --initrd=/var/www/cobbler/ks_mirror/ubuntu-11.10-server-amd64/install/netboot/ubuntu-installer/amd64/initrd.gz --arch=x86_64 --breed=ubuntu --ksmeta="directory=/cblr/links/ubuntu-11.10-server-amd64"
# cobbler profile add --name=ubuntu-11.10-server-amd64 --distro=ubuntu-11.10-server-amd64 --kickstart=/var/lib/cobbler/kickstarts/ubuntu-11.10-server-amd64.seed
最后我们需要 ubuntu 能完成自动安装，加入以下 kickstart 脚本 ubuntu-11.10-server-amd64.seed 到 /var/lib/cobbler/kickstarts/ :
# vi /var/lib/cobbler/kickstarts/ubuntu-11.10-server-amd64.seed
