New OpenGL management in Funtoo

Funtoo is switching to an improved system for managing multiple OpenGL providers (Mesa/Xorg, AMD and nVidia). The update may involve blockers and file collisions.

Lilo linux loader is a boot loader to load linux, and other operating systems. Lilo is called by default when running make install in kernel source directories.

Installation

Emerge

# emerge lilo

Configure

Lilo's default configuration example has hda references, lets change those to sda recursively using sed.

# sed -i -e 's/hda/sda/' /etc/lilo.conf.example

Now we copy the example configuration to the running configuration.

# cp /etc/lilo.conf.example /etc/lilo.conf

Default OS

To change default booting os.

/etc/lilo.conf
# MBR to install LILO to:
boot = /dev/sda
map = /boot/.map
default = Funtoo

Timeout

To have lilo auto start after a set time.

/etc/lilo.conf
# If you always want to see the prompt with a 15 second timeout:
timeout=150

Silence

For silent kernel decompression at boot:

/etc/lilo.conf
label = Funtoo
	read-only # read-only for checking
	append = "quiet"

alternate init systems

to load an alternate init system, example systemd instead of openrc:

/etc/lilo.conf
label = Funtoo-systemd
	read-only # read-only for checking
	append = "quiet init=/usr/lib/systemd/systemd"

Old Configs

It is a good idea to keep an old image around in case problems crop up in new kernel builds.

/etc/lilo.conf
#image = /boot/bzImage.old
        root = /dev/sda3
        #root = /devices/discs/disc0/part3
        label = funtoo.old
        read-only # read-only for checking#

Kernel Linking

Using symlinks is a good idea to be able to determine if the loader is loading the correct image, and enable tab auto completion to ensure we are loading what we intend to. symlinks remove an easy area to fumble when adjusting configurations.

# ln -s /boot/vmlinuz-version /boot/bzImage
# ln -s /boot/vmlinuz-version.old /boot/bzImage.old
Note

if you do not use make install to copy your kernel to /boot, you must run lilo to load the new kernel images & install lilo to the hard drives mbr

Install

Install lilo to the MBR.

# lilo
