From 7e61918f9d5d3c5bc1fb435ae9e6c8013cf5ab07 Mon Sep 17 00:00:00 2001 From: Arnout Vandecappelle Date: Tue, 6 Nov 2012 13:41:48 +0000 Subject: [PATCH] cpio/initramfs: clarify their use in the help text Recent mails on the list show that it is not very clear how to create an initial RAM fs with buildroot. So make this more explicit in the cpio and initramfs help texts. Hopefully this will reduce the /init debugging we have to do.
