Not 100% sure if we've given that any thorough testing, but the ops team is looking at most available options before building these out. That said, if they haven't tried it, they'll read this and give it a go :)
though i think a PXE or similar boot option would be a smarter move. just enough to bootstrap something to run in ram. (alternatively a minimal kernel and dedicate a section of the disks in the chassis to holding the running software (500MB x 45 with decent levels of erasure coding is a fairly minimal slice.) the kernel could then pull down the code after first boot (or updates)
