Homebrew Services logs don't exist on MacBook Pro M2 (arm64) after at least failed attempt to run dnscrypt-proxy

Homebrew Services doesn't seem to have any log files or directories, on a MacBook Pro M2 (arm64), after a failed attempt to run dnscrypt-proxy.

There don't seem to be any log directories:

$ brew services start dnscrypt-proxy
Warning: dnscrypt-proxy must be run as root to start at system startup!
==> Successfully started `dnscrypt-proxy` (label: homebrew.mxcl.dnscrypt-proxy)

Yeah, that looks correct based on the configuration in https://github.com/Homebrew/homebrew-core/blob/d44f6446e96137143853f35b77d0148ea9d4a1e0/Formula/d/dnscrypt-proxy.rb, none are defined

@SMillerDev: What's the directive that should be specified? Or what's an example of a formula with a service defined that has log output properly configured?

[SMillerDev]

They all have it configured properly, some just write to a specific file and some do not. If you are looking for an example of a formula with a specific error log, php has one. brew services info --debug --verbose <formula> can help you find information about the configured properties of services.
