Long boot time since systemd 251

Since upgrading to systemd251 (actual: 251.2-3)
my boottime has raised unaceptably:
Using systemd250 / (downgrading) this does not occur.

Some I-Net sources claims that for systemd251 there must be
“a differnet way / parameters to compile the kernel”

Most of the wait (20 seconds) happens before kernel gets even loaded. Something weird with your uefi loader.

But only with systemd251???

Yeah weird. :person_shrugging:

Looks like this bug:

sys-module-configfs.device has increased boot time · Issue #23850 · systemd/systemd · GitHub


It is not bug, but the performance is slowed down very little. I do not notice 2 sec difference.

Yes, “sys-module-configfs.device” too late

Ah, I mistakenly thought you are talking about those 20 seconds. Anyway, that doesn’t look normal either. :stuck_out_tongue:

Yeah, the 20 seconds are made by “Postboot-Time” in the ASUS-BIOS
