Run the update script to automatically generate new dependency lists. The result will be based on the published seed lists, filtered by:

• The Packages files (nonexistent packages will be skipped)
• debootstrap (packages not yet added to debootstrap will not be added to ubuntu-base)

Dependencies are debootstrap and germinate.

The changelog will be automatically updated, but make sure to run dch -r to change the distribution from UNRELEASED.
