From c299ec2d8e8d2f1a99d5c993fca485257b950d40 Mon Sep 17 00:00:00 2001 From: Alex Landau Date: Thu, 26 Apr 2007 00:17:29 -0700 Subject: [PATCH] kbuild: handle compressed cpio initramfs-es Make kbuild handle compressed cpio initramfs-es. An already compressed cpio is copied directly to usr/, while a non-compressed cpio is filtered through gzip (no changes here) on its way to usr/. If the user has created a compressed cpio by other means, this saves him from uncompressing it, just to be compressed again by kbuild.
