Heya, Since its early days systemd contained the systemd-readahead tool, whose job was to improve boot times by reading files in their order on disk, before they would actually be needed by applications. In times of SSD the benefit of systemd-readahead is much less convincing, in many case it actually slows things down.
The fact is now that nobody really cares about systemd-readahead much anymore. Nobody in the systemd team still works on a laptop with rotating media, hence nobody tries to optimize it in any way. And it probably needs a lot of looking after and love to still be useful as general purpose systems, instead of just slowing them down... So, I think with the release after the upcoming one we should just remove it from the systemd package and just throw it on the pile of historic cruft. So, yeah, here's the advance warning that this will be happening... (Well, unless somebody from the community who cares and wants to invest the necessary time in it steps up and gives it the love it really needs. If nobody does until that release, I will delete the component from systemd). I fully understand that not everybody uses SSDs yet, and also that theoretically doign systemd-readahead on SSD could be beneficial still (since RAM is still orders of magnitude faster than SSDs), but it's really not about that, it's about maintainership and giving the tool the love it needs.
