# - find scheduleworthy packages by pkgname/pkgbase (broken
#   dependencies, explicite regex) and their architecture
# - remove all ignored packages (seed-ignore, explicitely ignored,
#   blacklist)
# - run mysql_generate_package_metadata on each of them once (ignoring
#   the architecture for now)
