From 18b473ca9b3a1d050285af6c5d1640fafc5e0ecd Mon Sep 17 00:00:00 2001 From: Daniel Dickinson Date: Thu, 23 Sep 2010 13:58:05 +0000 Subject: [PATCH] base/block-extroot, base/block-mount: Modified preinit and block-extroot and block-mount so that use of block-mount and block-extroot do not require that block-extroot, block-mount, nor the kernel modules they depend, on are required to included in the image. That is block-extroot and dependencies may now be installed as modules onto the jffs2 part of a squashfs system and it will work. In addition packages which are installed into the jffs2 of a squashfs system may now affect preinit, so long as they do not require execution of commands that occur before the merging of the jffs2 and built-in (squashfs) preinit scripts is done. Thanks jow for the preinit merge stuff!
