Bug Description

ureadahead does not seem to be working at all these days - no profiles are being collected - and is the only thing left depending on libnih, so let's get rid of it, and then we can get rid of libnih as well.

[Original report]
Since on common platforms ureadahead solves nothing but causes a huge amount of garbage/totally useless error messages, which makes it really hard to extract the important messages from e.g. journalctl output, it should be removed from ubuntu-minimal. If there are people, who need it, can still explicitly install it.

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.

I dropped ureadahead from the standard seed git seconds ago.

Guys in almost all of my laptops and pcs I have spinning disks and in ubuntu 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 37s without).
In ubuntu 20.04 is now removed. I don't understand this approach, if it really was doing a significant difference. Not all people have or want SSDs! How can I install it in Ubuntu 20.04 if there is no available package now? I think there should be the option to install it if somebody wants it!! the package should remain available!!

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!!

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!!
