on POWER
PREFACE
This package is the LILO library of the bootloader configuration on
POWER
SYNOPSIS
use Bootloader::Core::PowerLILO;
"$obj_ref = Bootloader::Core::PowerLILO->new ();"
"$files_ref = Bootloader::Core::PowerLILO->ListFiles ();"
"$status = Bootloader::Core::PowerLILO->ParseLines (\%files,
$avoid_reading_device_map);"
"$files_ref = Bootloader::Core::PowerLILO->CreateLines ();"
"$status = Bootloader::Core::PowerLILO->UpdateBootloader
($avoid_init);"
"$status = Bootloader::Core::PowerLILO->InitializeBootloader ();"
DESCRIPTION
"$obj_ref = Bootloader::Core::PowerLILO->new ();"
Creates an instance of the Bootloader::Core::PowerLILO class.
"$settings_ref = Bootloader::Core::PowerLILO->GetSettings ();"
returns the complete settings in a hash. Does not read the settings
from the system, but returns internal structures.
"$files_ref = Bootloader::Core::PowerLILO->ListFiles ();"
Returns the list of the configuration files of the bootloader Returns
undef on fail
"$status = Bootloader::Core::PowerLILO->ParseLines (\%files,
$avoid_reading_device_map);"
Parses the contents of all files and stores the settings in the
internal structures. As first argument, it takes a hash reference,
where keys are file names and values are references to lists, each
member is one line of the file. As second argument, it takes a
boolean flag that, if set to a true value, causes it to skip updating
the internal device_map information. The latter argument is not used
for PowerLILO. Returns undef on fail, defined nonzero value on
success.
"$files_ref = Bootloader::Core::PowerLILO->CreateLines ();"
creates contents of all files from the internal structures. Returns
a hash reference in the same format as argument of ParseLines on
success, or undef on fail.
"$glob_info = $Bootloader::Core->Global2Info (\@glob_lines,
\@section_names);"
Gets the general information from the global section of the menu
file. This information usually means the default section, graphical
menu, timeout etc. As argument it takes a reference to the list of
hashes representing lines of the section, returns a reference to a
hash containing the important information.
"$lines_ref = Bootloader::Core->Info2Global (\%section_info,
\@section_names);"
Takes the info about the global options and uses it to construct the
list of lines. The info about global option also contains the
original lines. As parameter, takes the section info (reference to a
hash) and a list of sectino names, returns the lines (a list of
hashes).
"$lines_ref = Bootloader::Core->Info2Section (\%section_info,
\@section_names);"
Takes the info about the section and uses it to construct the list of
lines. The info about the section also contains the original lines.
As parameter, takes the section info (reference to a hash), returns
the lines (a list of hashes).
"$sectin_info_ref = Bootloader::Core->Section2Info (\@section_lines);"
Gets the information about the section. As argument, takes a
reference to the list of lines building the section, returns a
reference to a hash containing information about the section.
"$status = Bootloader::Core::PowerLILO->UpdateBootloader
($avoid_init);"
Updates the settings in the system. Backs original configuration
files up and replaces them with the ones with the '.new' suffix. Also
performs operations needed to make the change effect (run
'/sbin/lilo'). Returns undef on fail, defined nonzero value on
success.
"$status = Bootloader::Core::PowerLILO->InitializeBootloader ();"
Initializes the firmware to boot the bootloader. Returns undef on
fail, defined nonzero value otherwise
