| XXX: List of work required for Ubuntu Mobile kernel | For the Ubuntu Mobile and Embedded project we will have a separate Gutsy kernel flavour. This flavour will specify a kernel configuration optimized for the smaller and more restricted hardware that is typically used by mobile and embedded devices. |

The generic kernel configuration is intended to cater for the wide variety of hardware devices found on desktop and laptop systems. As such, the configuration specifies a large variety of devices and subsystems (e.g. ATM, SCSI drivers, filesystems) which are not necessary for the UME project. The UME flavour will have a reduced configuration which removes all unnecessary device drivers and subsystems. |

Summary
For the Ubuntu Mobile and Embedded project we will have a separate Gutsy kernel flavour. This flavour will specify a kernel configuration optimized for the smaller and more restricted hardware that is typically used by mobile and embedded devices.
Rationale
The generic kernel configuration is intended to cater for the wide variety of hardware devices found on desktop and laptop systems. As such, the configuration specifies a large variety of devices and subsystems (e.g. ATM, SCSI drivers, filesystems) which are not necessary for the UME project.
The UME flavour will have a reduced configuration which removes all unnecessary device drivers and subsystems.
Use Cases
Scope
The Gusty kernel build system already has the necessary infrastructure to handle different flavours. The aim of this work is to define the set of devices and subsystems which are definately not required for the UME, and to construct a customized kernel configuration accordingly.
Very little development work needs to be done for this.
Design
Implementation
This will be implemented within the existing Gusty kernel build infrastructure. It is anticipated that no substantial work is required.
Outstanding Issues
Need to determine the unnecessary drivers and subsystems.
