Thanks for responding. When I run this, I got this error:
Directory
'/gnu/store/jvj247prbwy1jn20svy4ls5yjscpmiss-xdg-mime-database/share/mime/packages'
does not exist!
My manifest file only installs racket and icedtea@2.6.6:jdk. If I rerun the
same command, I get "nothing to be done".
As a side note, is this the commonly recommended way to structure the
manifest file? The documentation for `guix package -m` instead says to use
`use-package-modules`, and doesn't mention anything about
`specification->package+output`.
