How is entropy loaded at startup, which causes the problem noted in github? If it's loaded before filesystems get mounted, that could be a problem for us, because /boot is on a different filesystem (msdosfs, to be read by petitboot). Petitboot also does not have a way to preload modules, so all we have at startup, until spawning init, is the kernel. - Justin
