NAME¶
elilo - install EFI boot loader
SYNOPSIS¶
elilo [
options]
DESCRIPTION¶
This manual page documents briefly the
elilo command, which was written
specifically for the Debian 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 Debian
GNU/Linux from the main filesystem to a subdirectory /EFI/debian 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 Debian GNU/Linux 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
