    Default Very long time booting after upgrading from 42.3 to 15.0

    Hi!
    I have recently upgraded my notebook from leap 42.3 to 15.0 (yes, I am a tad behind, sorry!) and I've found that boot takes much much longer than 42.3 or even than my laptop running Tumbleweed.
    I did a bit of research and I think there are two suspects:

    Code:
    # systemd-analyze blame  | head -20
        1min 30.131s clamd.service
             27.796s plymouth-quit-wait.service
             12.243s ca-certificates.service
              7.116s postfix.service
              6.817s display-manager.service
              6.410s SuSEfirewall2_init.service
              6.368s lvm2-monitor.service
              5.854s apparmor.service
              5.109s initrd-switch-root.service
              4.087s nscd.service
              4.080s alsa-restore.service
              3.995s bluetooth.service
              3.253s btrfsmaintenance-refresh.service
              2.550s windscribe.service
              2.175s polkit.service
              1.755s systemd-udevd.service
              1.634s fwupd.service
              1.630s SuSEfirewall2.service
              1.447s colord.service
              1.198s systemd-journal-flush.service
    clamd.service seems to take remarkably long. My question is, what can I do to fix this? or, where can I find more information about this problem?

    In the second place:
    Code:
    # grep resume /etc/default/grub
    GRUB_CMDLINE_LINUX_DEFAULT="resume=/dev/sda2 splash=silent quiet showopts resume=/dev/sda2 splash=silent quiet showopts resume=/dev/sda2 splash=silent quiet showopts resume=/dev/sda2 splash=silent quiet showopts"
    (where sda2 is the root partition)
    This looks rather repetitive, is it supposed to be like this? It doesn't look quite right. I've compared it to my Tumbleweed result running the same command and it doesn't repeat the same parameter, but I don't dare chopping it off without asking first.

    Perhaps these are all irrelevant, and I should be looking elsewhere? Leap does boot and runs smoothly, but it takes a surprisingly long time to do so.

    Thank you in advance for all the help and ideas that you can kindly provide.

    Did you modified the order of the boot sequence on your BIOS ?

    Yes, that looks repetitive. No, it is not supposed to look like that.

    I suggest you edit the file and clean that up (remove all repetitions). And then update "/boot/grub2/grub.cfg" so that the changes make it to there.

    It might be easier to use Yast bootloader to make those changes. Those repetitions will appear in the kernel parameters tab. And Yast will automatically update grub.cfg when you are done.

    Thank you so much for your kind reply, nrickert.

    I used yast bootloader to remove the repetitions, and it has improved, although it is still slower than 42.3, and most lines in the boot sequence appear twice. Hmm... Is there anywhere else I should look for info? Thank you once again!

    (Perhaps 15.0 is expected to be slower on the same machine 42.3 was running, in which case I might just need better hardware)

    Hi, Asimov, thanks for your kind reply. It doesn't seem to be a problem with the BIOS's boot sequence.

    Indeed. I don't use it, so don't know how much time it should consume, but AV software on Windows is a big resource gobbler. Does clamd take that long to startup on every boot?

    Fastest PC boot I seem to recall seeing reported was about 2.6 seconds, probably on linuxquestions.org forums.

    Hi, mrmazda! Thank you for your kind reply.

    The notebook in question is a bit old, but it's my most portable computer for field work, which is a large part of my job.

    Code:
    # inxi -GxxSCD

    I have been looking for information online on the clamd situation, because I had clamd running with 42.3 and I have it running with Tumbleweed (different computer though) and it doesn't even show up among the top 20 services when I do a systemd-analyze blame.
    I found this https://0xacab.org/leap/platform/issues/7683 but it seems old and in any case I can't get around to applying any of this to my situation. (Should I modify any file? If so, which one? How?)
    Perhaps this is all very obvious, and I apologize for my obtuseness, but I can't seem to find a solution by myself.

    Just suggestions, since I don't use clamd: look in /var/log. Does clamd have its own logging there? Are logs huge? Are logs getting rotated? Are logrotate and clamd configurations on your Bay Trail notebook and your TW laptop the same? Why are you using latest development kernel instead of 15.0 kernel? Is 15.0 a result of a series of upgrades going back to 13.1 or 13.2 without a fresh installation intervening?
