在Red Hat 5/6中,我是followed the documentation provided供应商.但是,我找不到Red Hat 7的等价物.具体来说,触摸/.unconfigured不会触发第一次启动设置.
9.3.1. Sealing a Linux Virtual Machine for Deployment as a Template
Summary
Generalize (seal) a Linux virtual machine before making it into a template. This prevents conflicts between virtual machines deployed from the template.Procedure 9.6. Sealing a Linux Virtual Machine
Log in to the virtual machine. Flag the system for re-configuration by running the following command as root:
# touch /.unconfigured- Remove ssh host keys. Run:
# rm -rf /etc/ssh/ssh_host_*- Set
HOSTNAME=localhost.localdomainin/etc/sysconfig/network- Remove /etc/udev/rules.d/70-*. Run:
# rm -rf /etc/udev/rules.d/70-*- Remove the HWADDR= and UUID= line from
/etc/sysconfig/network-scripts/ifcfg-eth*.- Optionally delete all the logs from
/var/logand build logs from/root.- Shut down the virtual machine. Run:
# poweroff
编辑：步骤1& 7可以通过运行sys-unconfig last来组合.或者,看一下来自libguestfs-tools-c的virt-sysprep,它可以做很多事情.

>初始设置,要求您接受许可并创建用户
> Firstboot,要求您配置kdump和(在RHEL上)设置您的订阅
现在通过systemd启用了这两个功能;一旦完成,他们就会自首.
因此,您应该做的就是删除在第一个初始安装过程中创建的任何本地用户并重新启用这些服务：
systemctl enable initial-setup-graphical.service systemctl enable firstboot-graphical.service > /etc/sysconfig/firstboot
并重新启动.
我不完全确定第三部分,它要求您提供语言并创建用户帐户或将计算机加入域.这至少会继续回来,直到你真正完成向导. (所以不要这样做.)
清理主机密钥和任何硬件特定配置仍然是一个好主意. (udev规则和接口配置文件中的Mac地址.)
