boot fail due to dbus and missing /efi at 2025/10/26 update

[Popolon]

Info: I use custom kernel without U/EFI.

Updated on 2025/10/26 with newly available update after 1 month without. After reboot, terminal display error on several services, but appily ssh started, I'm able to run startx from ssh, but not lightdm due to dbus. After connecting from another device via ssh, I noticed that the dbus-broker.service is the first failure.

journalctl -xeu dbus-broker.service display me that:

oct. 26 15:58:49 armitx (r-launch)[1155]: dbus-broker.service: Failed to set up mount namespacing: /efi: No such device
oct. 26 15:58:49 armitx (r-launch)[1155]: dbus-broker.service: Failed at step NAMESPACE spawning /usr/bin/dbus-broker-launch: No such device

But I didn't find where to disable efi dependency.

I noticed that efi is present in /etc/mtab:

systemd-1 /efi autofs rw,relatime,fd=60,pgrp=1,timeout=120,minproto=5,maxproto=5,direct,pipe_ino=20741 0 0

Does anyone have clue about where /efi is set in mounts?

I found a really dirty hack. I linked another partition to /efi in /etc/fstab, no everything launch fine, but I think it would be better to disable /efi mount at the standard OS place.

/dev/sdb3 /efi ext4 noauto 1 1

Strangly this partition isn't ever mounted...
