Preload does not install a systemd unit file. I take one from preload package on archlinux aur and attached that. Seems working for me. Reproducible: Always
Created attachment 372468 [details] Systemd unit file.
Created attachment 372470 [details] preload.service The first one was wrong pointed to preload.
I didn't add this on purpose: when running systemd would be much better to use its builtin readahead support (at least, it's supported while preload is dead for ages): http://www.freedesktop.org/software/systemd/man/systemd-readahead-replay.service.html Did you even tried it?
Oh, I didn't know systemd has it own readahead. I'll try it now. Thanks!
Using systemd builtin readahead instead.
