Error with daemon running through brew services

[fast-90]

Issue

When I start a daemon with brew start services emacs-plus, I get an "End of file during parsing: Error reading from stdin" error. The strange thing is that I don't get this error when I start a daemon with emacs --daemon in the terminal (after stopping the brew services).

Googling the error seems to suggest that there may be unbalanced parentheses in my config files, but as far as I can tell (visually and using check-parens) this does not seem to be the case.

Does anyone know what the problem might be? How would I go about debugging this further to pinpoint the root cause of the issue?

OK so I figured out that it is because of this line in my config:

(use-package consult
   :ensure-system-package (rg . ripgrep)

This line checks whether the rg binary exists, and I think the brew services does this in sudo mode and therefore requires me to enter my password (hence the "Error reading from stdin"). However, I have no clue how to solve this (i.e. to make brew services work with the above elisp code).

[d12frosted]

I don't think it's because of sudo (why and how would it run it as sudo?), but rather because launchctl runs Emacs in a different environment (ie login vs interactive). A bit of explanation can be found in a blog post where I explain why the PATH is injected.

Also I am curious, what exactly :ensure-system-package does. Also, do you use exec-path-from-shell?

In general, I'd say Emacs+ needs some love to make service more usable.
