bootlogd or bootchart? never really bothered with that tbh.
there's also systemd-bootchart, not sure if it's dependent on systemd, if not, maybe it can be used in devuan too.

Links to the .debs are in my exclamation mark (see fsmithred's post just above mine for bootlogd), along with an explanation of how to get bootchart working in chimaera.

And where is your exclamation mark?

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...

sed -i 's|#!/usr/bin/python|&3|' pybootchartgui.py
./pybootchartgui.py

EDIT: monkey patching ftw!

Thanks! And how analyze that? I see hdd is bottleneck?

Head_on_a_Stick · 2022-06-29 11:05:30

Looks like eudev takes forever. Do you have many devices connected?

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

deepforest · 2022-06-29 11:14:06

Yes, thx. i see long udevd.

usb mouse and usb hub, 2 sata hdd, nothing else

Noo, i am here because sysvinit

xinomilo · 2022-06-30 06:14:59

try removing devices one by one (i'd start with usb hub) and rebooting. see if/what device makes a difference.
if not, check boot messages... is "Waiting for /dev to be fully populated" step that is taking too long? (cause there are lots of eudev/init script issues around that one iirc.)

Head_on_a_Stick · 2022-06-30 15:05:20

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.
