zap init enabling auto updates bug

[fai-max]

zap init reveals a bunch of configurations that can be changed
upon enabling auto updates, it throws the following error

? Do you want to enable auto-update? Yes
2022/10/06 20:58:15 Probably not launched by systemd (please file an issue if this is wrong)
2022/10/06 20:58:15 /etc/systemd/user/zapd.service does not exist
2022/10/06 20:58:15 Creating ~/.config/systemd/user/zapd.service
[INFO]  2022/10/06 20:58:15 Restarting via systemd...

and proceeds to not display the other settings.

The above problem occurs only when enabling it. Disabling it lets it take its normal course.
