├╝ber-readahead is used during boot to read files in advance of when
they are needed such that they are already in the page cache,
improving boot performance.
Its data files are regenerated on the first boot after install, and
either monthly thereafter or when packages with init scripts or
configs are installed or updated.
ureadahead requires a kernel patch included in the Ubuntu kernel.
