Does the (untested) patch below solve the problem for you?
Perhaps it’s more appropriate than setting NIX_CONF_DIR.
Thanks,Ludo’.

No. I should have mentioned earlier. With this patch, the installphase will fail.

There is no obvious way to fix the error, so setting NIX_CONF_DIR iseasier. Perhaps someone can fix the nix package with a clean patch.That would be better.

Hi Peng Mei Yu,
I agree with Ludo' that fixing this at the package level is more ‘appropriate’ than in the service.

Obvious is different things to different people, but here's my go-to approach. Override the relevant variables during the install phase without changing any run-time settings:

It installs correctly. I didn't test the service.
Kind regards,

This is the clean patch I was asking for. The service works well on mycomputer. Thank you. Please push this patch.
