From 4c6f2eb979c314b6362e655f3ff15749af565f86 Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Thu, 10 May 2007 22:44:28 -0700 Subject: [PATCH] kbuild: add support for squashing uid/gid in gen_initramfs_list.sh Sometimes it is useful to squash all uid's/gid's to 0:0 regardless of current owner. For example, in build systems that get run as arbitrary users (uClinux-dist). This adds a special "squash" keyword so you can do '-g squash -u squash' and have ownership squashed to root.
