well, maybe a usb flash stick. I think that's what I'd do, and it would
be pretty cheap, reliable, fast, etc. the only thing on the flash stick
would be to fetch and boot the usual kernel/initrd configuration,
so the flash image would never need to change (and would be read-only,
so presumably not prone to wear. might need kexec if syslinux/etc can't
be persuaded to behave quite like this.

virtual media via BMC is a good idea, but sounds fragile and vendor-specific
