My kernel loading is slow so I ran a
journalctl -b
to see what was wrong and I saw that my kernel spent 4 seconds because ureadhead doesn't find some files, just as:
ott 25 14:01:29 andrea-Lenovo-Z50-70 ureadahead[255]: ureadahead:/var/lib/polkit-1/localauthority/10-vendor.d/unity-greeter.pkla: no such File o directory
or
ott 25 13:33:49 andrea-Lenovo-Z50-70 ureadahead[245]: ureadahead:/usr/sbin/lightdm: no such File or directory
(I use gdm and not lightdm)
There are 10-15 lines as that, relatives to software that I don't have on my PC. how can i tell ureadhead to don't start / don't find that because I don't have them and I don't want them? Thank you.
