The above line is the cause.
The error message is:

I don't really know ruby, but did the function name change?

[rycee]

Dunno, but yeah seems it's called exist now.

In any case, could you try using sd-switch instead? Like this:

systemd.user.startServices = "sd-switch";

[Mikilio]

Ok, that seems to work, but that also means that documentation needs to be updated to not imply that true and "sd-switch" are somehow equivalent.

[rycee]

They should be the same since a while back. Perhaps you haven't updated your HM pin for some time?

I'm also slowly working towards removing the Ruby tool entirely. It's in a branch at the moment but I hope to reasonably soon be ready to merge it: https://github.com/nix-community/home-manager/tree/rycee/default-systemd-start-services

Yes I just happened to update it sometime this week with a scary nix flake update But personally I won't push too hard on the doc. This can be closed imo.
