* gnu/packages/linux-initrd.scm: Remove. * gnu/system/linux-initrd.scm: New file. * gnu-system.am (GNU_SYSTEM_MODULES): Adjust accordingly. * gnu/system.scm (<operating-system>): Change default 'initrd' value to (gnu-system-initrd). (operating-system-derivation): Bind 'operating-system-initrd'. Pass 'menu-entry' an initrd file name instead of a package. * gnu/system/grub.scm (grub-configuration-file): Expect 'initrd' to be file name.
