We have in our lab a little LAN with a dozen Raspi 4B workstations and a potent LAMP server, that serves also DHCP, DNS, NFS and SMB. All workstations are identical: Monitor, USB-keyboard, -mouse and -barcode scanner, onboard LAN, 4GB RAM, current config as of now: EEPROM (26.4-1), Debian Bookworm (12.8), Chromium (130). Only a web browser is needed for our custom WebApp (data capture by filling out online forms), no disk storage required at all (like a read only public kiosk).
I’d like to simplify the setup by getting rid of all USB-SATA SSDs and introducing PXE in order to update in the future only one instance instead of many. I’m wondering if I could serve just one r/o image for all workstations by using symlinks on the r/o NFS share, since no writing is required on any workstation.
If I prepare one fresh SD-Card with all updates and define r/o overlay in raspi-config, I would assume, that I could take this SD-Card as base for the PXE image for all other workstations, without the need to modify anything else, except making symlinks on the NFS share for each serial number of each client. Identical hostnames due to the single unmodified config for all workstations should not play a role, since all unique FQDNs are defined in DNS and DHCP.
Do you think that's how it could work or have I misunderstood something?
