Hello) Here svg logs from Arch and Fedora36

Also perhaps check with a live ISO that boots with systemd to see how udev handles the devices.

Is there actually much delay when starting the desktop? It could be that the eudev stuff is done in the background after a working desktop is reached. I've seen that before with systemd-analyze output.

Ok, i will look exactly. I have at dual boot Arch and Fedora, all systems booting about same time.

Noo, i am here because sysvinit

You could try udev instead but that's from the systemd crowd so people might throw rotten fruit at you.

EDIT: monkey patching ftw!

It would have been *much* better to change the shebang in pybootchartgui.py instead of mangling your system. Remove that symlink.

So I presume you didn't boot with the required initcall_debug printk.time=y init=/sbin/bootchartd kernel parameters then?

This is like pulling teeth...
