Re: [solved] pam fails to find unit dbus-org.freedesktop.home1.service

I had the same problem and I think the error tells very clear what the issue is.
I solved it by making a symlink "dbus-org.freedesktop.home1.service" -> "systemd-hostnamed.service".
After this the log spam stopped.

Actually this is the real solution as dbus-org.freedesktop.home1.service is an alias to systemd-hostnamed.service (similar like dbus-org.freedesktop.oom1.service to systemd-oomd.service) but for whatever reason the symlink is (only for this one file) missing.

Upstream does not create the alias for dbus-org.freedesktop.home1.service [1].
It does for dbus-org.freedesktop.oom1.service but that is being removed in systemd 251 [2] as such links are meant to be dynamically installed when the service is enabled.

You're confusing hostnamed with homed.
systemd-hostnamed has an alias dbus-org.freedesktop.hostname1.service, but that has nothing to do with homed.

This is what you probably wanted instead:

sudo ln -s /usr/lib/systemd/system/systemd-homed.service /etc/systemd/system/dbus-org.freedesktop.home1.service

which results in  /etc/systemd/system/dbus-org.freedesktop.home1.service -> /usr/lib/systemd/system/systemd-homed.service

But this will result in systemctl list-unit-files reporting systemd-homed as enabled and the file will be removed if you systemctl disable systemd-homed.

Re: [solved] pam fails to find unit dbus-org.freedesktop.home1.service

So what is the proper solution/workaround  as of 2023? This little bugger is flooding my journal.

Re: [solved] pam fails to find unit dbus-org.freedesktop.home1.service

You can comment all pam_systemd_home.so lines in /etc/pam.d/* (mostly system-auth) but will have to adapt future changes to the file manually.
nb. that this is just spam and not an actual error (or indicative of one)

Re: [solved] pam fails to find unit dbus-org.freedesktop.home1.service

I have this in my pacman.conf, to avoid having to edit PAM config:

NoExtract   = usr/lib/security/pam_systemd_home.so

(and remove the file manually once)
