The mechanism that I’m familiar with booting Linux kernels and passing files in 
is via an initramfs that is specified along with the kernel name and boot args 
during boot either by grub or syslinux/extlinux.  The initramfs is essentially 
an cpio that provides a filesystem that overlays whatever is already in the 
root filesystem.  It’s a super convenient (relatively speaking) way of getting 
any needed files into the kernel.  From your question it sounds like Miorage 
does not support initramfs right now….


>the running unikernel 

The booting unikernel rather than the running unikernel.
