Yes – that’s one possible way. LINBO is one of the best core features of your new server and it’s a great way to keep every client clean from malware and let them repair by PXE-magic whenever it’s necessary.
We use a VM as master-client (but generally any client can be a master-client); one for Ubuntu-Clients and one for Win10. Whenever there’s a change (new software or anything else) it’s quite easy to start the VM on Proxmox, make all changes and upload a new full image to the server. There’s running a torrent-daemon on the linuxmuster-server. So the clients are seeders when they start via PXE. To get an impression of LINBO, I have attached an old photo. These monitors were changed meanwhile.
Multiboot is possible too as you can see in my picture. So far we don’t use Win11 but there’s a (not so long) thread about it in this forum.
And yes: you can setup some hardware classes (different hardware, non-compatible setups…) whenever it’s necessary. On Linux-clients we don’t need different images here as it runs on any client without problems. Windows is sometimes a bit more problematic but no need to panic.
You don’t need the proxmox snapshots for LINBO. Whenever an uploaded image doesn’t run on a second client you can simply upload a new one to the lmn-server and see if it works better. Depending on the software installed, the image can quickly become relatively large but nevertheless it works like a charm.
