Nice. |

Aside: I played with a PXELINUX (?) menu to boot a few different |
| 9 |
things. It's been too long for me to remember details. But I was quite |
| 10 |
happy with it. I think I had installers for a couple of different Linux |
| 11 |
distros and a couple of DOS based utilities. |

Fair enough. |

Okay. So there's no obvious conflict with UEFI and the OS DHCPing from |
| 22 |
the same MAC address. Relatively clean transition. |

Nice. |

(Kernel parameters moved to individual lines so my brain can absorb them.) |

So, there are three things DHCPing. |
| 33 |
|
| 34 |
1) UEFI firmware |
| 35 |
2) Kernel itself |
| 36 |
3) OS init scripts |
| 37 |
|

Intriguing. |

I had no idea that there was an nfs device. I am assuming that it's |
| 44 |
specific to the fact that the root file system type is NFS. - I must |
| 45 |
research this more. |

I assume: |
| 51 |
|
| 52 |
"ServerIP" is the NFS server's IP address. |
| 53 |
|
| 54 |
"/diskless" is the NFS export |
| 55 |
|
| 56 |
"/root,nolock,fsc,tcp,proto=tcp,vers=4,nfsvers=4.2,rsize=1048576,wsize=1048576" |
| 57 |
are NFS mount options. |

Why have a raid parameter? Is there something in the kernel that you |
| 62 |
don't need and are disabling? Or is this somehow influencing how file |
| 63 |
systems are mounted on boot? |
| 64 |
|
| 65 |
Do OS init scripts try to remount root? Or is there not an entry in |
| 66 |
/etc/fstab for the root, and just rely on the kernel's mount? |

Hum. |
| 73 |
|
| 74 |
How are you handling the hostnames? Or is that dynamic? |
| 75 |
|
| 76 |
What about user accounts? Are all your client systems using the same |
| 77 |
password & group files? |
| 78 |
|
| 79 |
What about SSH host keys? |

I can see that for logs. But I don't think that an empty tmpfs is |
| 85 |
sufficient for things like passwd / group files or ssh host keys. |

Thank you for the link and kindling something that's been a latent |
