====
|
|
Provide dpkg specific image building glue.
|
|
|
|
The ubuntu element needs customisations at the start and end of the image build
|
|
process that do not apply to RPM distributions, such as using the host machine
|
|
HTTP proxy when installing packages. These customisations live here, where they
|
|
can be used by any dpkg based element.
|
|
|
|
The dpkg specific version of install-packages is also kept here.
