Yeah, it seems reasonable. Also we can avoid env by conditionally
passing --homedir to gpg. But the parameter should maybe live in package
consfigurator? Then what about the functions in data/util.lisp?
gpg-file-as-string can certainly reference the parameter by qualified
path, but maybe it would be less confusing to just move everything in
data/util.lisp into util.lisp?
