How Can I Speed Up My Fedora Boot Time?

Another thing you could do is disable any services you're not actively using. For instance, if you don't use any features tied to `tpmrm` or serial devices, you can disable their services as well. Just be cautious about the dependencies - always double-check if they won't affect anything crucial. Also, have you considered a lighter desktop environment if speed is your top priority?

First off, 5.6 seconds for `NetworkManager-wait-online.service` is quite long. Since you mentioned you've already disabled that service, you might want to consider looking into some of the other services such as the `sys-module-fuse.device` or `sys-devices-platform-serial8250`. If you're not using FUSE or those serial devices, disabling them might help you shave off some time at boot. Also, check for any unnecessary services that could be disabled using `systemctl`!

To speed things up, try customizing your boot parameters as well. You can adjust the kernel options in your bootloader to include things like disabling certain hardware checks that your system might not need during startup. Just be ready to do some testing to find the right balance between speed and functionality!
