Yersterday I upgraded another old laptop from ubuntu 18.04 to ubuntu
20.04 and I see 35 secs slower boot. Guys really ureadahead made a huge
impact. Please reconsider enabling it again. I cannot understand how you
decided to drop it before doing any real life tests!!

Have you guys really run real life tests before taking the decision to
remove it? If I can see 21% less booting time by using it in ubuntu
18.04 then it is really doing something and 21% less booting time is
really something important!! Please reconsider your decision!!

18.04 where ureadahead was preinstalled I noticed that was actually doing a
great job (had 20secs difference: 1min 17s boot time with ureadahead and 1min

Title:
Remove ureadahead and libnih
To manage notifications about this bug go to:

Further rationale:
* /var/lib/ureadahead is empty on cosmic, so no data is being collected
* with SSDs being more common place these days, readahead is mostly pointless,
or even harmful
* systemd also removed their readahead.
