1. Ansible: Hey MAC address `xx:xx:xx:xx:xx:xx`, wake up!
|
|
2. Machine: Hello everyone, I just woke up in network mode, could someone please show me how to boot?
|
|
3. DHCP server: I hear you, here's your IP address, proceed to the next server to obtain your bootloader.
|
|
4. Machine: Hello, could you please send me my bootloader?
|
|
5. TFTP server: Here you go. Grab your boot configuration, kernel, and initial ramdisk as well.
|
|
6. Machine: Hi, I just booted into my bootloader, and my boot parameters instructed me to get the installation instructions, packages, etc. from this site.
|
|
7. HTTP server: It's all yours.
|
|
8. Machine: Great, now I can install the OS and reboot!
