SYNOPSIS

       lilo-uuid-diskid [-h] [-v] [lilo.conf]

DESCRIPTION

       This script looks for the boot block device or boot partition and create the right diskid or uuid as boot option. Then it looks for all

       -h  Print a brief help.

       -v  Print verbose messages.

EXAMPLES

       Lines in the configuration file /etc/lilo.conf:

	 #boot = /dev/sda
	 boot = /dev/disk/by-id/ata-SAMSUNG_SV1604N_S01FJ10X999999

	 #root = /dev/sda1
	 root = "UUID=/dev/disk/by-uuid/18843936-00f9-4df0-a373-000d05a5dd44"
