Thanks, alkisg ! Bonding has worked for something similar for me in the past; I just wasn't sure how to bond before the network mounts. I will look into initramfs-tools.

j_sh: (in case you see the logs) actually on second thought it should be possible to just create the bond on POST_INITRD_BOTTOM_x, as you'll be reusing the same IP, so you don't even need to unmount and re-mount the NFS share

Hello, somebody knows lan software to throw surveys in class?
It's best to ask in your distribution for this as it's not ltsp-specific

I read somewhere that ltsp only really works with GNOME or MATE, is that true or not?
I've tested it with MATE, GNOME, KDE, XFCE, LXDE and LXQT, but it should work in all the other ones as well. It even works without a DE.
With LTSP, does this mean I have have a fleet of low spec computers be used to connect to a powerful server even if I was doing say video editing?
No. It just means that you need to maintain one installation instead of many. It doesn't change what you can do with your computers.
I thought LTSP made it possible to share resources with many different computers.
No, it's not related to clustering. With LTSP, you can netboot many computers from the same image. That image has the same abilities as if it was installed locally.
It can e.g. have x2go or xrdp installed, and with that, you can do "remote desktop" to a powerful server, this is somewhat called "thin clients"
But without x2go/xrdp, it's just normal netbooted "fat" clients, that run the apps locally with their own CPU/RAM/GPU
And if I used xrdp, I can then use a powerful GPU/CPU even if the local computer doesn't have that installed?
Yes, but note that remote desktop has a latency when updating the screen
E.g. if you play youtube, you see 5-10 fps, not 30-60 fps
You think that just having each computer be as powerful as the LTSP server be more ideal?
I think that fat clients are better suited for desktop workstations, and powerful servers for running math programs or other intensive long running tasks
So, ltsp fat clients in general should meet the Ubuntu/Debian/whatever recommended hardware requirements
Thin clients are fine for tasks that don't require a lot of video updates, e.g. not for web surfing
So a basic i5 dell computer with be ideal for a "fat client" that would connect to the powerful server and do demanding tasks on the fat client?
E.g. for schools here, I recommend an i3 with 4 GB RAM. While for my own office, I prefer i5 with 8 GB RAM.
i5 with 8GB of RAM for the local fat client or the server itself?
For the fat client. The server doesn't really need to be powerful, it just needs a fast local disk
https://ubuntu.com/download/desktop => recommended requirements: 4 GB system memory
Of course if you install e.g. lxde, and don't run a browser, you can boot clients with less than 512 MB RAM
But for web surfing etc, you should follow the recommended requirements of the distribution and DE you choose
What specs do you recommend for the fat client if we're talking about multimedia such as video editing, video encoding, streaming video, GIMP, and so on?
Well it depends; for a school I would say i3 with 8 GB RAM; for a professional multimedia environment, they might need 16 GB RAM or even more
That part isn't related to LTSP, it's the same as local installations
LTSP will just put your installation on the network instead of on a local disk
It doesn't change the requirements or the running speed
A professional that opens an image of 5000x5000 pixels needs more RAM than a hobbyist that opens an HD image
Okay, that makes sense. I was under the false impression I could do anything on any specs because the server would handle the entire load itself, even down to GPUs.
If you use x2go, then that's the case. But for desktop stuff, it's not worth it to invest to a powerful server and cheap clients.
Thanks, I'll keep the server and clients as equals.
Ten i5 clients with 4 or 8 GB RAM, will run a whole lot better than a server with ten times more powerful CPU, and 40 or 80 GB RAM. Plus, they'll be cheaper.
What makes LTSP special compared to a regular netboot and using NFS outside of LTSP?
Regular netboot is for a single client
LTSP adds some magic to simplify netbooting, global configuration, multiple clients via overlayfs from the same readonly image, pam authentication for logins etc
It's all in the ltsp.org start page
