Does Guix have a declarative Guix API way of knowing if it is installing a package into foreign distro versus Guix System?
I'm thinking of a function like `foreign-distro?`: ``` (define-public peek (package (name "peek") ... (inputs `(,@(if (foreign-distro?) `(("ffmpeg" ,ffmpeg)) '()))) ``` The above includes ffmpeg in the inputs only if installing peek on a foreign distro. It could additionally patch the ffmpeg executable in a peek package phases if foreign-distro? returns #t. WDYT
