    Fedora 28 - slow boot time

    Good afternoon all,

    I installed Fedora 28 on my HP 17,3 " Intel Core i5-7200U, 2x 2.50GHz, 8GB DDR4 RAM, 1TB HDD, AMD Radeon 520, 2GB, HDMI notebook.

    Performing a "systemd-analyze" command via terminal leads to a total boot time (kernel, user space, graphical environment) of about 1,46 minutes.

    I used to use Debian for a long time within the same notebook and under Debian 9 the boot time was about 36 seconds.

    Performing a "systemd-analyze critical-chain" command does not help me any further at all, the only "slow" service is "libvirt" with about 6 extra seconds, the other services are rather inconspicuous.

    So is it because of Selinux that Fedora boots extremely slow in general or are there any other things to keep in mind ? Debian uses Apparmor btw. and lasts only one third compared to Fedora.

    Even a bloated Ubuntu 18.04 only needs about one minute to boot. So I am helpless.

    BTW the "kernel not configured for semaphores" - bug at shutdown known since Fedora 26 also appears.

    Thank you in advance for your help.


    Update: After performing a "dracut -fv" plus after autorelabeling systemd via "touch /. autorelabel" boot time increased and now Fedora 28 takes 1,09 minutes to boot - 37 seconds faster than before. I can live with that. The annoying "kernel not compiled for semaphores" - bug unfortunately still exists since version 26 - no one seems to be interested in solving it, sad but true.
