Nice.
Aside: I played with a PXELINUX (?) menu to boot a few different
things. It's been too long for me to remember details. But I was quite
happy with it. I think I had installers for a couple of different Linux
distros and a couple of DOS based utilities.
I've had this same IP for months on this machine, I would assume
the same for the others,
Fair enough.
as far as log messages from the server, it answers the same to each
request from the same mac as far back I I've scrolled through
Okay. So there's no obvious conflict with UEFI and the OS DHCPing from
the same MAC address. Relatively clean transition.
Yes all are booting the same kernel
Nice.
(Kernel parameters moved to individual lines so my brain can absorb them.)
ip=dhcp
So, there are three things DHCPing.
1) UEFI firmware
2) Kernel itself
3) OS init scripts
Intriguing.
root=/dev/nfs
rootfstype=nfs
I had no idea that there was an nfs device. I am assuming that it's
specific to the fact that the root file system type is NFS. - I must
research this more.
rw
nfsroot=ServerIP:/diskless
/root,nolock,fsc,tcp,proto=tcp,vers=4,nfsvers=4.2,rsize=1048576,wsize=1048576
I assume:
"ServerIP" is the NFS server's IP address.
"/diskless" is the NFS export
"/root,nolock,fsc,tcp,proto=tcp,vers=4,nfsvers=4.2,rsize=1048576,wsize=1048576"
are NFS mount options.
raid=noautodetect
Why have a raid parameter? Is there something in the kernel that you
don't need and are disabling? Or is this somehow influencing how file
systems are mounted on boot?
Do OS init scripts try to remount root? Or is there not an entry in
/etc/fstab for the root, and just rely on the kernel's mount?
all the same root, I actually just have a custom bash script in local.d
(openrc) for handling specifics for each node (adding dvd/blueray whatever
to fstab)
Hum.
How are you handling the hostnames? Or is that dynamic?
What about user accounts? Are all your client systems using the same
password & group files?
What about SSH host keys?
anything that conflicts like /var/log I just have as tmpfs on
each machine
I can see that for logs. But I don't think that an empty tmpfs is
sufficient for things like passwd / group files or ssh host keys.
https://wiki.gentoo.org/wiki/Diskless_nodes I got my start from
reading that, well unless you count doing diskless with ubuntu in the
way way past, my hard drive died then and I wasn't about to just use a
livedvd unable to really install anything lol

Thank you for the link and kindling something that's been a latent
interest of mine.
