But it just occurred to me that you could write: (define (default-nginx-config log-directory run-directory) (plain-file "nginx.conf" (string-append ...))) Problem solved! (‘text-file*’ is more advanced: Instead of returning a file in the store, it returns a *derivation* that builds a file possibly containing references to store items. But here, the default config file does not refer to any store item, so ‘plain-file’ is enough.) WDYT? Thanks, Ludo’.
