# and what can actually be updated.
# Specifically, to solve a dependency:
# - look at packages to_install
# - look at installed packages
#   - if it's marked to_update, then we must process the update first
#   - if it's marked as installed, or as cant_update, or uptodate, then
#   we can use the installed packages.
#   - otherwise, in update mode, put a request to update the package (e.g.,
#   create a new UpdateSet.

# Update/Dependencies can do its job.
