From 8f51399e75e5d0d0741ecb18c549a57840bd1cc3 Mon Sep 17 00:00:00 2001 From: Harald Hoyer Date: Tue, 30 Apr 2013 18:01:47 +0200 Subject: kernel-install: add default install scripts Do the depmod in the kernel-install hooks, so hooks can produce/install kernel modules and be part of the depmod. Also move the basic boot loader entry creation and removal to a plugin script. If PRETTY_NAME is not defined in /etc/os-release, fallback to PRETTY_NAME="Linux $KERNEL_VERSION". Add documentation for everything in the man page. --- src/kernel-install/50-depmod.install | 8 ++++ src/kernel-install/90-loaderentry.install | 77 +++++++++++++++++++++++++++++++ src/kernel-install/kernel-install | 68 +++++---------------------- 3 files changed, 96 insertions(+), 57 deletions(-) create mode 100644 src/kernel-install/50-depmod.install create mode 100644 src/kernel-install/90-loaderentry.install (limited to 'src/kernel-install') diff --git a/src/kernel-install/50-depmod.install b/src/kernel-install/50-depmod.install new file mode 100644 index 0000000000..68c24bed7a --- /dev/null +++ b/src/kernel-install/50-depmod.install @@ -0,0 +1,8 @@ +#!/bin/bash +# -*- mode: shell-script; indent-tabs-mode: nil; sh-basic-offset: 4; -*- +# ex: ts=8 sw=4 sts=4 et filetype=sh + +[[ $1 == "add" ]] || exit 0 +[[ $2 ]] || exit 1 + +exec depmod -a "$2" diff --git a/src/kernel-install/90-loaderentry.install b/src/kernel-install/90-loaderentry.install new file mode 100644 index 0000000000..55b4d24672 --- /dev/null +++ b/src/kernel-install/90-loaderentry.install @@ -0,0 +1,77 @@ +#!/bin/bash +# -*- mode: shell-script; indent-tabs-mode: nil; sh-basic-offset: 4; -*- +# ex: ts=8 sw=4 sts=4 et filetype=sh + +COMMAND="$1" +KERNEL_VERSION="$2" +BOOT_DIR_ABS="$3" +KERNEL_IMAGE="$4" + +if [[ -f /etc/machine-id ]]; then + read MACHINE_ID < /etc/machine-id +fi + +if !
