I want to replace configuration file contents using Propellor, but some configuration files are long so I want to keep them outside config.hs and without having to use quotation. I came up with this: ``` {-# LANGUAGE TemplateHaskell #-} module Utility.Embed where import Language.Haskell.TH import qualified Data.FileEmbed as FE sourceFile :: FilePath -> Q Exp sourceFile path = return . AppE (VarE 'lines) =<< FE.embedStringFile path ``` Which can be used like this: ``` standardSystem :: HostName -> Host standardSystem hn = host hn & Apt.installed ["heimdal-clients"] & "/etc/krb5.conf" `File.hasContent` $(sourceFile "files/etc/krb5.conf") ``` What do you think, is this the right approach or should I just read source files with the IO monad?
