This week there are quite a lot of changes but most are just related to changes in the organisational structure of the Informatics computing team. Several other changes are preparatory work for the introduction of a new installer for Ubuntu. Here are all the details…

Unit Changes

Lots of headers have been tweaked to reflect the demise of the Infrastructure Unit and the change of name for the Managed Platforms Unit which has become the Systems Unit.

Preseeding Debian packages

There are two new macros which make it easier to preseed options for Debian packages at install time. They can be used like this:

LCFG_PRESEED_PKG(tzdata,tzdata)

LCFG_PRESEED(tzdata,Areas,select,Europe)
LCFG_PRESEED(tzdata,Zones,select,London)
!install.pre_var_tzdata_Zones mSET(Zones/Europe)

Note that you must specify the package first before configuring the options. As usual the key (e.g. tzdata) may be any valid LCFG tag name. The macros are designed for the common, simple cases, if the option name is not a valid LCFG tag (e.g. contains a forward slash) then an additional resource must be specified.

The order of the header inclusions in the top-level lcfg header – lcfg/defaults.h – has been tweaked slightly to allow these new macros to be used in the headers for other components.

Localisation

There is a new header for configuring all the common localisation parameters – lcfg/options/l10n.h – this is used in the new LCFG installer to preseed various package options prior to installation. Some of this configuration was previously specified in the internationalisation header – lcfg/options/i18n.h – which was not really the most suitable location.

Sleep component

Various headers have been modified to make it clear that the LCFG sleep component will not be ported to the Ubuntu platform.

Package Options

The following new package options have been added to Ubuntu:

• LCFG_OPTIONS_CMAKE – cross-platform, open-source make system
• LCFG_OPTIONS_COROSYNC – cluster engine daemon and utilities
• LCFG_OPTIONS_OPENSSH_CLIENT – secure shell (SSH) client
• LCFG_OPTIONS_PACEMAKER – cluster resource manager
• LCFG_OPTIONS_PCS – Pacemaker Configuration System

There has also been some refactoring of other options to extract common dependencies which has caused a certain amount of churn.
