Bootloaders do not care about content of initrd, they just load it in
memory and pass pointer to kernel.

Not that I'm aware of. I have the same issue every now and then and it
would be good to have dracut support it. Something like "lsinitrd -x"
to extract archives and dracut options to use existing directories for
early cpio and main initrd.
