NAME
elilo - install EFI boot loader
SYNOPSIS
elilo
[options]
DESCRIPTION
This manual page documents briefly the
elilo
command, which was written specifically for the Ubuntu distribution to
simplify configuring and using the elilo.efi bootloader.
There are two parts to elilo, the bootloader itself and this utility which
installs or updates a bootload configuration.
The primary function of elilo is to copy files necessary for booting
Ubuntu from the main filesystem to a subdirectory /EFI/ubuntu
on the boot partition. These include elilo.efi, elilo.conf, and the kernel
and ramdisk images referenced by elilo.conf.
In addition, elilo can create a default
configuration file, /etc/elilo.conf, and can invoke efibootmgr to create
an entry in the EFI Boot Manager menu such that a system will autoboot
in to Ubuntu on power up.
elilo
requires a couple of extra parameters in elilo.conf that elio.efi does
not currently support.
These are needed so that a normal run of elilo with no parameters can find
the elilo.efi binary and boot partition in order to rebuild it.
They are:
install=<path to elilo.efi>
boot=<boot partition>
OPTIONS
This program follows the usual GNU command line syntax, with long
options starting with two dashes (`-').
-b, --boot
set bootstrap partition device [ -b /dev/sda1 ]
-i, --install
pathname to the actual bootloader binary,
default: /usr/{local/}lib/elilo/elilo.efi
-C, --config
use alternate configuration file [ -C config_file ]
--autoconf
auto-generate a /etc/elilo.conf. Typically only used during system
installation. In normal use, an elilo.conf file already exists and will not
be modified by elilo.
--efiboot
elilo auto configuration: create an efi boot manager entry for elilo. This
option requires that the
efibootmgr
package also be installed.
--timeout
elilo auto configuration: sets the time elilo
will wait for user input before booting default
image default: 20 (2 seconds)
--image
elilo auto configuration: sets the path to the
kernel image. default: /vmlinuz
--label
elilo auto configuration: sets the image label
default: Linux
--root
elilo auto configuration: sets the root device default: /dev/sda3
--format
create a new FAT filesystem on the boot partition. Use this cautiously if
you have more than one operating system installed, and they may be sharing
the same EFI partition!
-v, --verbose
make elilo more verbose
--debug
print boring junk only useful for debugging
-h, --help
display this help and exit
-V, --version
output version information and exit
