That essentially means the ROMS and the keymaps. The keymaps are safe as those are loaded at initial startup only. I think the ROMs are safe too, since again they are loaded during startup. The only caveat is whether any boards re-load ROMs during a guest reboot ? I think probably not, but not 100% sure.
