Details:
I've developed a patch which implement few related features:
- ability to define which linux kernels and in which order will be shown in
top menu instead of one auto-detected latest kernel
- ability to show kernel version in simple menu items, to distinguish between
several items added by previous feature
- ability to use custom kernel command line parameters for some kernels
instead of GRUB_CMDLINE_LINUX_DEFAULT
Here is my real use-case explaining needs in these features. I'm experimenting
with switching between proprietary nvidia driver and nouveau. My main kernel
is 3.10.1-hardened-r1 (for proprietary nvidia driver), and I've also compiled
experimental kernel with "_nouveau" local version:
3.10.1-hardened-r1_nouveau.
First issue - auto-detect of latest kernel choose 3.10.1-hardened-r1_nouveau,
which is wrong for me, and only way to change this is add some fake local
version for main kernel just to make sure it will be sorted before "_nouveau"
string.
Second issue - main kernel need "vga=" parameter, while nouveau kernel need
"video=" parameter, but there is no way to configure this.
Third issue - I'd like to have both normal and nouveau kernels in main menu,
in manually defined order.
Attached patch is for grub-2.00_p5107.
All these features configurable using /etc/default/grub using two new
variables (GRUB_SIMPLE_VERSION and GRUB_MENU_LINUX) and one user-defined
function (grub_cmdline_linux_custom). Example:
# Add kernel version to simple menu entries
GRUB_SIMPLE_VERSION=true
# Manually define list of simple menu entries instead of auto-detecting
# latest kernel.
GRUB_MENU_LINUX="
/boot/vmlinuz-3.10.1-hardened-r1
/boot/vmlinuz-3.10.1-hardened-r1_nouveau
"
# Append parameters to the linux kernel command line for non-recovery entries
GRUB_CMDLINE_LINUX_DEFAULT="vga=0x315"
# Append parameters to the linux kernel command line for non-recovery entries
# for some kernels (instead of GRUB_CMDLINE_LINUX_DEFAULT)
function grub_cmdline_linux_custom {
local -A CMDLINE
CMDLINE[3.10.1-hardened-r1_nouveau]="video=800x600"
echo ${CMDLINE[$1]}
}
