# This script creates a virtual installed package named
|
|
# kernel-backup-${KERNEL_VERSION}-${ARCH}-${BUILD}, which
|
|
# consists of a backup of /boot/vmlinuz-${KERNEL_VERSION}-generic
|
|
# to /boot/vmlinuz-${KERNEL_VERSION}-backup, and the modules that
|
|
# go with this kernel. If there's a matching initrd already created,
|
|
# we'll include that too. Otherwise, we'll assume you don't want one
|
|
# or that you'll manage it yourself outside of the installed backup
|
|
# package.
|
|
#
|
|
# By default, it makes a backup of the kernel pointed to by
|
|
# /boot/vmlinuz-generic. Once backed up, this kernel can be added to
|
|
# your bootloader as a fallback kernel, and removing or upgrading the
|
|
# original kernel-generic package will not remove it. But, you can
|
|
# remove the kernel-backup package later with removepkg if you wish.
|
|
#
|
|
# The $KERNEL_FILE doesn't need to have any particular naming scheme.
|
|
# You could point at /usr/src/linux/arch/x86/boot/bzImage for all this
|
|
# script cares. The kernel modules do need to be installed first though.

PACKAGE DESCRIPTION:

kernel-${BACKUP_NAME}: kernel-${BACKUP_NAME} (backup of ${KERNEL_FILE})
|
|
kernel-${BACKUP_NAME}:
|
|
kernel-${BACKUP_NAME}: This is a Linux kernel with built-in support for SATA, NVMe, and most
|
|
kernel-${BACKUP_NAME}: commonly used filesystems, as well as a large collection of loadable
|
|
kernel-${BACKUP_NAME}: kernel modules.
|
|
kernel-${BACKUP_NAME}:
|
|
kernel-${BACKUP_NAME}: It is recommended to use an initrd with this kernel for best results.
|
|
kernel-${BACKUP_NAME}: For more information about creating an initrd, see the README.initrd

kernel-${BACKUP_NAME}: file in the /boot directory.
