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
root ##i### emerge lilo
Configure
Lilo's default configuration example has hda references, lets change those to sda recursively using sed.root ##i### sed -i -e 's/hda/sda/' /etc/lilo.conf.exampleNow we copy the example configuration to the running configuration.
root ##i### 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.
root ##i### ln -s /boot/vmlinuz-version /boot/bzImage
root ##i### ln -s /boot/vmlinuz-version.old /boot/bzImage.old
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.root ##i### lilo
