Gregory Haynes 45df304d48 Perform package install outside of debootstrap
Debootstrap only supports one apt repository to install packages from.
As a result, we do not consider the updates repo during debootstrap
causing us install a second kernel when we do an apt-get dist-upgrade
during build.

Lets use debootstrap to get us a minimal chroot, then add our repos and
install the correct packages from the start.

We also have to reorder the dpkg root.d scripts which configure apt so
they run before we perform our package installs.

dpkg

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.

Environment Variables

DIB_APT_KEYS
Required

No

Default

None

Description

If an extra or updated apt key is needed then define DIB_ADD_APT_KEYS with the path to a folder. Any key files inside will be added to the key ring before any apt-get commands take place.

Example

DIB_APT_KEYS=/etc/apt/trusted.gpg.d

DIB_APT_LOCAL_CACHE
Required

No

Default

1

Description

By default the $DIB_IMAGE_CACHE/apt/$DISTRO_NAME directory is mounted in /var/cache/apt/archives to cache the .deb files downloaded during the image creation. Use this variable if you wish to disable the internal cache of the /var/cache/apt/archives directory

Example

DIB_APT_LOCAL_CACHE=0 will disable internal caching.

DIB_DISABLE_APT_CLEANUP
Required

No

Default

0

Description

At the end of a dib run we clean the apt cache to keep the image size as small as possible. Use this variable to prevent cleaning the apt cache at the end of a dib run.

Example

DIB_DISABLE_APT_CLEANUP=1 will disable cleanup.
