@flokli you mean for systemd-homed? first I have to understad it :-). I'm currently trying to rebuild my pc, and then figure out how homed works.

Should I add systemd-homed.service to upstreamSystemUnits in nixos/modules/system/boot/systemd.nix?
Not exactly sure how I would enable that unit if I include it in upstreamSystemUnits.

Suggestion: add a Co-Authored-By mention of @kirelagin to acknowledge his initial work on this :)

@kloenk is this ready for review?

We might want to degrade this to a draft PR until it has proven to work, and has a test ensuring it stays that way ;-)

Oh, yeah. It's a draft.
But I think I can't change it right now, as I only have my phone with me.

I think the way to continue with this should be:

• figuring out how and what can be used from systemd-homed
• write a nixos module, which then enables the systemd-homed service
• write tests

I think the way to continue with this should be:

* [ ]  figuring out how and what can be used from systemd-homed

* [ ]  write a nixos module, which then enables the systemd-homed service

* [ ]  write tests

I installed that systemd on my main machine xD.
I can now create users via homectl create test and see via userdbctl user test that it was created via homectl. Is this a good thing to test?

I'd really prefer if we'd first address the PAM issues mentioned by Archlinux, and include a test, before shipping this in master.

I agree on including this as a package. The module can be contributed later, and those who feel brave enough could try the new tech on their machines or VMs and help contributing the aforementioned module.

I would totally install this on a VM for testing!

Can we add a enableHomed flag, which still is set to false in our default systemd derivation?

That'd mean we won't ship untested features enabled by default, but people can get a systemd with homed, without rebuilding the world, by slightly overriding systemd.package.

Pity draft PRs don't get their conflict status updated. This certainly has cosmetic conflicts with #101886.

Also, do we have an issue on our end for the PAM debacle?

Will try to rebase and recheck tomorrow

Rebased, not yet tested if it builds and works

I successfully built both systemd and systemd.overrideAttrs ( old: { withHomed = true; } ).
