Mostly figuring out how to test it! On my machine at home, `guix home reconfigure` can take minutes. And some errors don't actually show up. After trying different solutions, I eventually settled on the following: while developing, I add, at the end of service file, something like: ```scheme (define configuration (home-service-configuration ; […] ) (mixed-text-file "test" (serialize-configuration configuration home-service-configuration-fields)) ``` And then I run: ```console > cat (guix build -f path/to/home/service.scm) # … the content of the generated file ``` I can only test file generation, though. Then I painfully discovered that replacing in a string is not as easy as it sounds, or, more precisely, that "python replace in string" yields better results than "scheme replace in string" in DuckDuckGo! I've also used `gexp` in places where I'm not sure it makes any sense, but it works, so… #pragmatic! > > At least now one of them [1] looks like a decent home service.

Done! <https://issues.guix.gnu.org/62969> I could have done a **lot** more with the documentation, but I wanted to be sure to get the basic right first. -- Tanguy
