[root@server1 ~]# cobbler check
The following are potential configuration items that you may want to fix:
1 : some network boot-loaders are missing from /var/lib/cobbler/loaders, you may run 'cobbler get-loaders' to download them, or, if you only want to handle x86/x86_64 netbooting, you may ensure that you have installed a *recent* version of the syslinux package installed and can ignore this message entirely. Files in this directory, should you want to support all architectures, should include pxelinux.0, menu.c32, elilo.efi, and yaboot. The 'cobbler get-loaders' command is the easiest way to resolve these requirements.
2 : debmirror package is not installed, it will be required to manage debian deployments and repositories
3 : The default password used by the sample templates for newly installed machines (default_password_crypted in /etc/cobbler/settings) is still set to 'cobbler' and should be changed, try: "openssl passwd -1 -salt 'random-phrase-here' 'your-password-here'" to generate new one
Restart cobblerd and then run 'cobbler sync' to apply changes.

# thinkpad 这个是随机的数字或字母用来干扰以免被人看到 123456为root密码
