From c535eabfd26a1927fc87adb9250e277e19a66c3c Mon Sep 17 00:00:00 2001 From: Pascal Rigaux Date: Tue, 29 Jun 2004 04:54:42 +0000 Subject: - add scripts/remove-boot-splash so we can modify a bootsplash from an initrd without having to rebuild it - make-boot-splash doesn't try to detect the resolution anymore, it now needs to be given one - in switch-themes and remove-theme, use bootloader-config to update the bootloader - remove detect-resolution - requires new mkinitrd (old mkinitrd used detect-resolution) - remove "Patch: glibc-fixed-header.tar.bz2" which is unused (and not in CVS) --- scripts/Makefile | 2 +- scripts/detect-resolution | 143 --------------------------------------------- scripts/make-boot-splash | 18 +++--- scripts/remove-boot-splash | 34 +++++++++++ scripts/remove-theme | 15 +---- scripts/switch-themes | 15 +---- 6 files changed, 47 insertions(+), 180 deletions(-) delete mode 100755 scripts/detect-resolution create mode 100644 scripts/remove-boot-splash (limited to 'scripts') diff --git a/scripts/Makefile b/scripts/Makefile index c82b9db..6b46046 100644 --- a/scripts/Makefile +++ b/scripts/Makefile @@ -1,4 +1,4 @@ -PL=detect-resolution +PL=remove-boot-splash SH=make-boot-splash rewritejpeg switch-themes remove-theme SBIN=splash.sh SYS=bootsplash.sysconfig diff --git a/scripts/detect-resolution b/scripts/detect-resolution deleted file mode 100755 index 3021f95..0000000 --- a/scripts/detect-resolution +++ /dev/null @@ -1,143 +0,0 @@ -#!/usr/bin/perl -# -*- Mode: cperl -*- -# Copyright (C) 2002 by Chmouel Boudjnah -# Redistribution of this file is permitted under the terms of the GNU -# Public License (GPL) -# -# Detect vga resolution we want. -# -# add better detection thanks to Olivier Blin idea to use argument from -# make_boot_splash. - -use strict; -my (%main, %entry, $vga, $initrd); - -if ($ARGV[0]) { - $initrd = -l $ARGV[0] ?
