I have a couple of dell 3000 sff boxes that I would like to setup as a IncusOS cluster. I used IncusOS image downloader to create a usb file and used balena etcher to write the usb key and then discovered that these dell 3k systems did not want to boot from usb. I’m probably missing some setting but I have been using them with ipxe to install alpine for other testing so I know that works.
Interesting question, will properly need this to at some stage.
I would create a very generic USB image from the IncusOS image downloader, just provide a certificate and very basic network settings. Convert the USB image into a PXE boot image, configure PXE boot and see if it is booting….
Think the trick is to convert the USB into a boot able PXE binary and to keep IncusOS config as simple as possible.
