My plymouth remains using too much loadtime...

I´m trying to reduce my TOO LONG boottime... I went from 1min 16sec. down to 1min 1sec. by disabling a lot of services which I don´t use.

I also disabled: plymouth.quit.wait.service

But then when I write: systemd-analyze blame, it shows plymouth.quit.wait.service(even after I disabled it...)

When I write: systemctl status plymouth.quit.wait.service, then it says: No such file or directory. Inactive(dead)

That makes no sense to me!

Isnt it possible to disable plymouth service ?

Thank in advanced

Disable ModemManager if you are not using a modem.

Why is your firewalld taking so long?

You can also try minimizing the time systemd-journal takes. See here for problem, and here for solution

Yes, I use a modem.

I also wonder why my firewalld is taking so long...but how to find out if I use ipt ? Because otherwise I would disable my firewallld...

I don't know how to find out why your firewall is taking so long but I do know that it is not worth disabling it to save 10s during your boot. How often do you reboot? Once a day? So what do the 10 secs matter?

Welcome to ask.fedora! There are, actually, two ways to keep a service from running at boot. Disabling it, as you did, only stops it from starting on its own; any other service that needs it (or, at least, thinks it needs it) can still start it, and that's probably what's happening here. If you want to make it stay dead until you decide otherwise, run this as root: systemctl mask plymouth.quit.wait.service and it won't be possible to start it via systemctl until you unmask it.

You might also want to run systemd-analyze critical-chain (You don't need root for this.) and see which services depend on which, and what other bottlenecks you have. Good luck, and let us know what happens.

After I did mask the plymouth, it still says that it takes 34 sec. to load...

After I used this code: mv /var/log/journal /var/log/ I gained about 3 sec...

After I used critcal-chain it says: @49.593s └─ @49.593s └─libvirtd.service @25.201s +5.704s └─ @25.187s └─wpa_supplicant.service @27.084s +422ms └─dbus.service @12.323s └─ @12.315s └─ @12.315s └─iscsiuio.socket @12.315s └─ @12.290s └─systemd-update-utmp.service @12.173s +115ms └─auditd.service @12.105s +66ms └─systemd-tmpfiles-setup.service @11.693s +339ms └─fedora-import-state.service @11.372s +316ms └─ @11.294s └─run-user-42.mount @21.890s └─ @4.658s └─systemd-tmpfiles-setup-dev.service @4.065s +591ms └─kmod-static-nodes.service @3.163s +162ms └─system.slice └─-.slice

So what you're saying is, it now takes only 44.7% as much time as it did before, but it's not good enough. Sorry, but nothing else jumps out at me as a possibility. Maybe somebody else has an idea.

Plymouth was just confusing me, cause it didn´t seem to get masked...

Well, have a nice day! :-)
